I entered upon ʿAbdur-Rahman bin Abi Laila, who told me that he heard ʿAli ؓ say in ar-Rahbah: I adjure by Allah any man who heard the Messenger of Allah ﷺ and was present on the day of Ghadeer Khumm to stand up, and no one is to stand up except those who saw him. Twelve men stood up and said: We saw and heard him when he took him by the hand and said, ʿO Allah, take as friends those who take him as a friend, and take as enemies those who take him as an enemy, support those who support him and forsake those who forsake him.ʿ Everyone stood up except three. He prayed against them and his supplication against them was fulfilled.  

سَمِعَ رَسُولَ اللهِ ﷺ وَشَهِدَهُ يَوْمَ غَدِيرِ خُمٍّ إِلا قَامَ وَلا يَقُومُ إِلا مَنْ قَدْ رَآهُ فَقَامَ اثْنَا عَشَرَ رَجُلًا فَقَالُوا قَدْ رَأَيْنَاهُوَسَمِعْنَاهُ حَيْثُ أَخَذَ بِيَدِهِ يَقُولُ اللهُمَّ وَالِ مَنْ وَالاهُ وَعَادِ مَنْ عَادَاهُ وَانْصُرْ مَنْ نَصَرَهُ وَاخْذُلْ مَنْ خَذَلَهُ فَقَامَ إِلا ثَلاثَةٌ لَمْ يَقُومُوا فَدَعَا عَلَيْهِمْ فَأَصَابَتْهُمْ دَعْوَتُهُ
