The first part of verse 16:90 says:
"Allah enjoins justice, generosity and kind treatment with kindred."
The verse 16:90 is being recited in Jumuah khutbas every Friday in millions of Masajid throughout the world since the time of Umar bin Abdul Aziz (may Allah T'ala be please with him).
The first of these three commandments of Allah T'ala is justice which has two aspects.
To make such arrangements as may enable everyone to get one's due rights without stint. Justice does not, however, mean equal distribution of rights, for that would be absolutely unnatural. In fact, justice means equitable dispensation of rights which in certain cases may mean equality. For example, aII citizens should have equal rights of citizenship but in other cases equality in rights would be injustice. For instance, equality in social status and rights between parents and their children will obviously be wrong. Likewise those who render services of superior and inferior types cannot be equal in regard to wages and salaries. What AIIah enjoins is that the full rights of everyone should be honestly rendered whether those be moral, social, economic legal or political in accordance with what one justly deserves.
Speaking about Prophet Muhammad (s.a.a.w.), Allah T'ala says in the Holy Quran:
Morality is an important aspect of Islam. In the Islamic terminology it is called “khuluq” and its plural is “akhlaq”. There are two aspects of a human being: one is “khalq” that is the physical aspect and the appearance. The other is “khuluq” and that is character, behavior and inner dispositions. Islam emphasizes that we take care of our physical appearance by keeping it clean, properly covered, healthy and nourished with Halal food and drinks. In a similar way it tells us that we should take care of our character and behavior.
قَالَ ابْنُ عَبَّاسٍ كَانَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ أَجْوَدَ النَّاسِ وَأَجْوَدُ مَا يَكُونُ فِي رَمَضَانَ وَقَالَ أَبُو ذَرٍّ لَمَّا بَلَغَهُ مَبْعَثُ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ لِأَخِيهِ ارْكَبْ إِلَى هَذَا الْوَادِي فَاسْمَعْ مِنْ قَوْلِهِ فَرَجَعَ فَقَالَ رَأَيْتُهُ يَأْمُرُ بِمَكَارِمِ الْأَخْلَاقِ (البخاري )
Ibn ‘Abbas reports that the Prophet -peace be upon him- was the most generous person. He used to become even more generous in Ramadan. And Abu Dharr said that when he heard about the coming of the Prophet -peace be upon him- he said to his brother, ‘Go to this valley and hear his words.’ He returned and said to him, ‘I saw him commanding people about the noblest morals and manners.’ (Al-Bukhari)
The Prophet was sent by Allah to teach the humanity the noblest morals (makarim al-akhlaq). He said,
عَنْ أَبِي هُرَيْرَةَ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ أَكْمَلُ الْمُؤْمِنِينَ إِيمَانًا أَحْسَنُهُمْ خُلُقًا وَخِيَارُكُمْ خِيَارُكُمْ لِنِسَائِهِمْ خُلُقًا (الترمذى
“The most perfect believer in faith is the one who is best in moral character. The best of you are those who are the best to their spouses in manners.” (al-Tirmidhi 1082)
عَنْ عَائِشَةَ قَالَتْ سَمِعْتُ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَقُولُ إِنَّ الْمُؤْمِنَ يُدْرِكُ بِحُسْنِ خُلُقِهِ دَرَجَاتِ قَائِمِ اللَّيْلِ صَائِمِ النَّهَارِ (مسند أحمد
‘Aishah -may Allah be pleased with her- said, “I heard the Prophet -peace be upon him- say, ‘Indeed the believer by his good morals reaches the ranks of those who spend the whole night in prayer and whole day in fasting. (Musnad Ahmad, 23219)
عَنْ أَبِي الدَّرْدَاءِ قَالَ سَمِعْتُ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَقُولُ مَا مِنْ شَيْءٍ يُوضَعُ فِي الْمِيزَانِ أَثْقَلُ مِنْ حُسْنِ الْخُلُقِ وَإِنَّ صَاحِبَ حُسْنِ الْخُلُقِ لَيَبْلُغُ بِهِ دَرَجَةَ صَاحِبِ الصَّوْمِ وَالصَّلَاةِ (الترمذي
Abu al-Darda’ reports that I heard the Prophet -peace be upon him- say, “There is nothing in the Balance heavier than the good morals. Indeed the person of good morals will reach by them the rank of the person of fasts and prayers.” (al-Tirmidhi 1926)
There are many Ahadith that indicate the high place of morals and manners in Islam. The good morals and manners should be observed in one’s personal life as well as in one’s relations with others.
Some Ahadith on Islamic manners:
عَنْ عَبْدِ اللَّهِ بْنِ عَمْرٍو رَضِيَ اللَّهُ عَنْهُمَا عَنْ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ الْمُسْلِمُ مَنْ سَلِمَ الْمُسْلِمُونَ مِنْ لِسَانِهِ وَيَدِهِ وَالْمُهَاجِرُ مَنْ هَجَرَ مَا نَهَى اللَّهُ عَنْهُ )البخاري
“The Muslim is he/she from whose hand and tongue other Muslims are safe and Muhajir is he/she who leaves what Allah has forbidden.” (al-Bukahri 9)
حَدَّثَنَا قَتَادَةُ عَنْ أَنَسٍ عَنْ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ لَا يُؤْمِنُ أَحَدُكُمْ حَتَّى يُحِبَّ لِأَخِيهِ مَا يُحِبُّ لِنَفْسِهِ (البخاري
“None of you will be a believer until he loves for his brother what he loves for himself.” (al-Bukhari 12)
عَنْ أَبِي هُرَيْرَةَ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ لَا يَدْخُلُ الْجَنَّةَ مَنْ لَا يَأْمَنُ جَارُهُ بَوَائِقَهُ (مسلم
“He will not enter heaven whose neighbor is not safe from his troubles.” (Muslim 66)
عَنْ أَبِي هُرَيْرَةَ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ الْإِيمَانُ بِضْعٌ وَسَبْعُونَ أَوْ بِضْعٌ وَسِتُّونَ شُعْبَةً فَأَفْضَلُهَا قَوْلُ لَا إِلَهَ إِلَّا اللَّهُ وَأَدْنَاهَا إِمَاطَةُ الْأَذَى عَنْ الطَّرِيقِ وَالْحَيَاءُ شُعْبَةٌ مِنْ الْإِيمَانِ (مسلم
Faith has more than seventy branches (or he said more than sixty branches). The supreme branch is the statement that ‘There is no god except Allah’ and the lowest branch is the removal of obstacles from the path. The modesty is a branch of faith.” (Muslim 51)
These issues are not small; they are very important. No macro change can come without the micro change. Bad manners have sometimes drastic social affects.
Some of you may have heard of some interesting research on crime, called the “broken window” effect. Two researchers did the following test. They put one car in the poorer areas of New York, with the hood open. They put another car in a really affluent suburb in California. The car in New York got pulled to pieces within 24 hours. The car in California remained untouched for two weeks. Then one of the researchers smashed one window in the car and within a day, the car ended up like the one in New York.
They concluded that by breaking the window on the car, they essentially marked the car as “neglected” and thus people thought of it as “fair game”, even though it was in a good neighbourhood. Similarly, the authors concluded, if you allow little things to get away, like the breaking of windows, unless the window gets fixed very soon, all the windows get smashed.
Three years ago, in New York, they had a new police commissioner. He decided to implement this idea, by ensuring that the police no longer just attack the big issues, the homicides, the car stealings, the breaking and entering; but also the little things, like making sure streets were clean, fixing broken windows. The net effect? Crime rates in New York, formerly one of the world's crime centres, fell by almost one third in three years. Why does this work? By taking care of the little things, you give people a sense of security.
We observe good morals and manners to obey Allah and His Messenger. This is part of our faith. Our faith leads to good morals and manners and they in their turn reinforce our faith. On the other hand, we should also keep in mind the best da’wah is to live among people with good morals and manners. Before listening to our message people see us and our behavior. Non-Muslims sometimes say when they see the bad example of Muslims, “If your religion has not made you a good person, how can it be a good religion for us.” We have a big responsibility and we must take our actions seriously.

Khutbah at ISOC - 24 Shawwal 1421/ January 19, 2001 By Dr. Muzammil H. Siddiqi
When there was nothing, Allah T'ala was, and when there will be nothing, He will be. He is the most Manifest of all the manifest, for whatever manifests itself in the world, does only by His attributes and His works and His light. And He is the Most Hidden of all the hidden, for not only do the senses fail to percieve Him but the intellect and thought and imagination also cannot attain to His essence and reality.
The best commentary in this regard are the words of a supplication of the Holy Prophet (upon whom be Allah's peace and blessings). which Imam Ahmad, Muslim, Tirmidhi, and Baihaqi have related on the authority of Hadrat Abu Hurairah, and Hafiz Abu Ya'la Mosuli in his Musnad on the authority of Hadrat 'A'ishah:
"Antal Awwal, fa-laisa qablaka shai'in; wa Antal Akhir fa-laisa ba 'daka shai 'in; wa Antal Zahir, fa-laisa fauqaka shai in; wa Antal Batin, fa laisa dunaka shai'in. " "You alone are the First; none is before You; You alone are the Last: none is after You; You alone are the Exalted none is above You; You alone are the Hidden: none is more hidden than You. "
Here, the question arises: How does this accord with the immortality and eternal life of the dwellers of Paradise and Hell mentioned in the Qur'an when Allah alone is the Last and Eternal? Its answer has been provided by the Qur'an itself: "Everything is perishable except Allah Himself." (AI-Qasas: 88). In other words no creature is immortal in its personal capacity; if a thing exists or continues to exist, it does so because Allah keeps it so, and can exist only by His letting it exist; otherwise in its own capacity everything is perishable except Allah. Immortality in Heaven and Hell will not be bestowed upon somebody because he is immortal by himself, but because AIIah will grant him eternal life. The same is true of the angels: they are not immortal by themselves. When Allah willed they came into existence, and will continue to exist only as long as He wills.
