REVEALED at Minā during the Prophet’s Farewell Pilgrimage in the month of Dhu ’l-Hijjah, 10 H. – that is, a little over two months before his death – this is unquestionably the last complete sūrah conveyed by him to the world. It was preceded one day earlier (on Friday, the 9th of Dhu ’l-Hijjah) by the revelation of the words, “Today have I perfected your religious law for you, and bestowed upon you the full measure of My blessings, and willed that self-surrender unto Me (al-islām) shall be your religion” (5:3); and since those words were almost immediately followed by the present sūrah, some of the Prophet’s Companions concluded that his mission was fulfilled, and that he was about to die (Bukhārī). As a matter of fact, the only revelation which the Prophet received after An-Nasr was verse 281 of Al-Baqarah.
بِسمِ اللَّهِ الرَّحمـٰنِ الرَّحيمِ إِذا جاءَ نَصرُ اللَّهِ وَالفَتحُ
WHEN GOD'S SUCCOUR comes, and victory,
وَرَأَيتَ النّاسَ يَدخُلونَ في دينِ اللَّهِ أَفواجًا
and thou seest people enter God's religion1 in hosts,
فَسَبِّح بِحَمدِ رَبِّكَ وَاستَغفِرهُ ۚ إِنَّهُ كانَ تَوّابًا
extol thy Sustainer's limitless glory, and praise Him, and seek His forgiveness: for, behold, He is ever an acceptor of repentance.2
