‘Ali adjured the people at ar-Rahbah, saying: Whoever heard the messenger of Allah ﷺ speak on the day of Ghadeer Khumm, let him stand up. And (of the people) around Sa’eed, six men stood up, and (of the people) around Zaid, six men stood up, and they testified that they had heard the Messenger of Allah ﷺ say to ‘Ali ؓ on the day of Ghadeer Khumm. “Isnʿt it Allah Who is closer to the believers?” They said: Yes. He said: ʿO Allah, if I am a personʿs mawla (friend and supporter) then ‘Ali is also his mawla; O Allah, take as friends those who take him as a friend, and take as enemies those who take him as an enemy.” A hadeeth like that of Abu Ishaq was narrated from ʿAmr Dhi Murr, i.e., from Saʿeed and Zaid, and he added to it: ʿand support those who support him, and forsake those who forsake him.ʿ A similar report was narrated from Abut-Tufail from Zaid bin Arqam from the Prophet ﷺ.
سَمِعَ رَسُولَ اللهِ ﷺ يَقُولُ يَوْمَ غَدِيرِ خُمٍّ إِلا قَامَ قَالَ فَقَامَ مِنْ قِبَلِ سَعِيدٍ سِتَّةٌ وَمِنْ قِبَلِ زَيْدٍ سِتَّةٌ فَشَهِدُوا أَنَّهُمْ سَمِعُوا رَسُولَ اللهِ ﷺ يَقُولُ لِعَلِيٍّ يَوْمَ غَدِيرِ خُمٍّ أَلَيْسَ اللهُ أَوْلَى بِالْمُؤْمِنِينَ؟ قَالُوا بَلَى قَالَ اللهُمَّ مَنْ كُنْتُ مَوْلاهُ فَعَلِيٌّ مَوْلاهُ اللهُمَّ وَالِ مَنْ وَالاهُ وَعَادِ مَنْ عَادَاهُ
