Allah T'ala sent the Prophet Muhammad (s.a.a.w.) as شَاهِدً
Allah T'ala says in the Holy Quran:
يَا أَيُّهَا النَّبِيُّ إِنَّا أَرْسَلْنَاكَ شَاهِدًا وَمُبَشِّرًا وَنَذِيرًا
O Prophet, We have sent you as a witness, a bearer of good news and a warner. (33:45)Read more...
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)
Muhammad (s.a.a.w.) preached to the people to trust in Allah (swt). His whole life was a sublime example of the precept. In the loneliness of Makkah, in the midst of persecution and danger, in adversity and tribulations, and in the thick of enemies in the battles of Uhud and Hunain, complete faith and trust in Allah (swt) appears as the dominant feature in his life. However great the danger that confronted him, he never lost hope and never allowed himself to be unduly agitated. Abu Talib knew the feelings of the Quraish when the Prophet (s.a.a.w.) started his mission. He also knew the lengths to which the Quraish could go, and requested the Prophet (s.a.a.w.) to abandon his mission, but the latter calmly replied,
"Dear uncle, do not go by my loneliness. Truth will not go unsupported for long. The whole of Arabia and beyond will one day espouse its cause." [Ibn Hisham, Sirat-ur-Rasul]
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.
