I heard ‘Ali ؓ say: I was the first man to pray with the Messenger of Allah ﷺ. It was narrated that Habbah al-Urani said: I heard Ali ؓ say: I was the first who prayed with the Messenger of Allah ﷺ. (Using translation from Aḥmad 1191)
سَمِعْتُ عَليًّا يَقُولُ أَنَا أَوَّلُ مَنْ صَلَّى مَعَ رَسُولِ اللهِ ﷺ
