Allah T'ala says in the Holy Quran:
(4:148) Allah does not like speaking evil publicly unless one has been wronged. Allah is All-Hearing, All-Knowing.
(4:149) (Even though you have the right to speak evil if you are wronged), if you keep doing good -whether openly or secretly -or at least pardon the evil (then that is the attribute of Allah). Allah is All-Pardoning and He has all the power to chastise.
The Prophet (s.a.a.w.) enjoined upon Muslims to treat the poor kindly and to help them with alms, Zakat, and in other ways. He said: "He is not a perfect Muslim who eats his fill and lets his neighbor go hungry."
He asked, "Do you love your Creator? Then love your fellow beings first."
Monopoly is unlawful in Islam and he preached that "It is difficult for a man laden with riches to climb the steep path that leads to bliss."
He did not prohibit or discourage the acquisition of wealth but insisted that it be lawfully acquired by honest means and that a portion of it would go to the poor. He advised his followers
"To give the laborer his wages before his perspiration dried up."
He did not encourage beggary either and stated that
"Allah is gracious to him who earns his living by his own labour, and that if a man begs to increase his property, Allah will diminish it and whoever has food for the day, it is prohibited for him to beg."
To his wife he said, "O A'isha, love the poor and let them come to you and Allah will draw you near to Himself." [Sahih Bukhari]
One or two instances of the Prophet's (s.a.a.w.) concern for the poor may be given here. A Madinan, Ibad Bin Sharjil, was once starving. He entered an orchard and picked some fruit. The owner of the orchard gave him a sound beating and stripped off his clothes. The poor man appealed to the Prophet (s.a.a.w.) who remonstrated the owner thus:
"This man was ignorant, you should have dispelled his ignorance; he was hungry, you should have fed him."
His clothes were restored to the Madinan and, in addition, some grain was given to him [Abu Dawood]
A debtor, Jabir Bin Abdullah, was being harassed by his creditor as he could not clear his debt owing to the failure of his date crop. The Prophet (s.a.a.w.) went with Jabir to the house of the creditor and pleaded with him to give Jabir some more time but the creditor was not prepared to oblige. The Prophet (s.a.a.w.) then went to the oasis and having seen for himself that the crop was really poor, he again approached the creditor with no better result. He then rested for some time and approached the creditor for a third time but the latter was adamant. The Prophet (s.a.a.w.) went again to the orchard and asked Jabir to pluck the dates. As Allah would have it, the collection not only sufficed to clear the dues but left something to spare. [Sahih Bukhari]
His love for the poor was so deep that he used to pray: "O Allah, keep me poor in my life and at my death and raise me at resurrection among those who are poor." [Nasai]
Abdullah ibn Amr narrated:
"Allah's Messenger (s.a.a.w.) neither spoke in an insulting manner nor did he ever speak evil intentionally. He used to say, 'The most beloved to me among you is the one who has the best character and manners.'" (Narrated by Al-Bukhari)
AbuHurayrah narrated that the Prophet (s.a.a.w.) said:
"The most Perfect believer in respect of faith is he who is best of them in manners." (Narrated by Abu-Dawood)
Qatadah ibn Malik narrated that Zayd ibn Ilaqah related on the authority of his uncle, Qatadah ibn Malik, that the Prophet (s.a.a.w.) would supplicate:
"O Allah, I seek Your protection against undesirable manners, acts, and desires." (Transmitted by Al-Tirmithi.)
Anas ibn Malik narrated:
"I was walking with the messenger of Allah (s.a.a.w.) and he was wearing a mantle of Najran with a thick border. A Bedouin met him and pulled the mantle so violently that I saw this violent pulling had left marks from its border on the skin of the neck of the Messenger of Allah (s.a.a.w.). And he (the Bedouin) said: Muhammad!, command that I should be given out of the wealth of Allah which is at your disposal. The Messenger of Allah (s.a.a.w.) turned to him and smiled, and then he ordered for him a provision."
He also narrated:
"Eighty men from the men of Makkah descended upon the Messenger of Allah (s.a.a.w.) from the mountain of Al-Taneem, in [full] armor, with the intent of doing battle with him. He (Muhammad, s.a.a.w.) captured them peaceably and then did not kill them" (Narrated by Muslim)
"By the grace of Allah, you are gentle towards the people; if you had been stern and harsh-hearted, they would have dispersed from round about you." The noble Qur'an, A'al-Umran(3):159
The following is a Hadith from the books of Bukhari and Muslim:
Hadrat Anas ibn Malik (may Allah be pleased with him) said: While we were in the mosque with Allah's Messenger (may Allah's blessings and peace be upon him) a desert Arab came and began to pass water in the mosque. The companions of Allah's Messenger said, "Stop! Stop!" but Allah's Messenger (may Allah's blessings and peace be upon him) said, "Don't interrupt him; leave him alone." They left him alone, and when he had finished, Allah's Messenger (may Allah's blessings and peace be upon him) called him and said to him, "These mosques are not suitable places for urine and filth, but are only for remembrance of Allah, prayer and recitation of the Qur'an," or however Allah's Messenger expressed it.* Hadrat Ibne Malik (may Allah be pleased with him) said that he then gave orders to one of the people who brought a bucket and poured water over it. (Bukhari and Muslim)
*Indicating that the transmitter is not sure of the exact words.
When his wet-nurse, Halima al-Sa‘dia, first saw him, she laid her hand on him and he smiled. "When he smiled," she said, "a light appeared from his mouth that rose to the sky."[32. Bayhaqi, Abu Nu'aym, ibn Ishaq and Abu Ya'la.]
Some of the hadiths we have quoted here have strong chains of transmission, others have weaker ones. However, we must remember that even the chain considered weakest by Muslim traditionists, is quite acceptable as historical proof to any professional historian on this planet, being far stronger and better authenticated than other ancient sources he works with. It is also well known that weak traditions strengthen each other so as to become acceptable. This is why those we have quoted here have been accepted by leading scholars such as Ibn Kathir, Suyutiī, Qadi ‘Iyad, Bayhaqi, and others.
Commenting on the verse of Qur’an,"There has come to you a light from Allah and a clear Book,"[33. Qur'an (5:15)] the well-known scholar al-Alusi says that the light in question is no other than the Prophet, may Allah’s blessings and peace be upon him. He quotes the Follower, Qatada, as an authoritative source for this opinion, as well as other well known scholars, pointing out that this is the most logical interpretation of the construction of the verse, Then he also quotes those whose opinion differs from his in that they believe that both the light and the Book refer to the Qur’an. This he does because real Muslim scholars, as opposed to pretenders and impostors, always quote, along with their own opinions, the contrary opinions of other reputable scholars, so weighing both in the most objective manner. Qadi ‘Iyad, the famous author of al-Shifa’, is of the same opinion as al-Alusi, an opinion, an opinion shared by other famous commentators such as Tabari and Qurtubi.
