Abdullah ibn Amr reported: The Messenger of Allah, peace and blessings be upon him, came out to us one day as if to say farewell. The Prophet said, “I am Muhammad, the unlettered prophet. There is no prophet after me. I have been given words that are eloquent, comprehensive, and decisive. I know how many angels guard the Hellfire and carry the Throne. Leniency came through me and I was pardoned along with my nation. Thus, listen and obey me as long as I am among you. When I am taken away, then you must adhere to the Book of Allah. Make lawful what it declares to be lawful and forbid what it declares to be forbidden.”

عَنْ عَبْدِ اللهِ بْنِ عَمْرِو بْنِ الْعَاصِ قَالَ خَرَجَ عَلَيْنَا رَسُولُ اللهِ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ يَوْمًا كَالْمُوَدِّعِ فَقَالَ أَنَا مُحَمَّدٌ النَّبِيُّ الْأُمِّيُّ وَلَا نَبِيَّ بَعْدِي أُوتِيتُ فَوَاتِحَ الْكَلِمِ وَجَوَامِعَهُ وَخَوَاتِمَهُ وَعَلِمْتُ كَمْ خَزَنَةُ النَّارِ وَحَمَلَةُ الْعَرْشِ وَتُجُوِّزَ بِي وَعُوفِيتُ وَعُوفِيَتْ أُمَّتِي فَاسْمَعُوا وَأَطِيعُوا مَا دُمْتُ فِيكُمْ فَإِذَا ذُهِبَ بِي فَعَلَيْكُمْ بِكِتَابِ اللهِ أَحِلُّوا حَلَالَهُ وَحَرِّمُوا حَرَامَهُ
