(Imām Bukhārī narrates): Mūsā ibn Ismā'īl narrated to us, he said: Hammām narrated to us, from al-A'lam, and he is Ziyād, from al-Hasan, from Abī Bakrah:
he went to the Prophet ﷺ; at that time he was in rukū'. He performed rukū' before reaching the row, then he mentioned this to the Prophet ﷺ, so he said: May Allāh increase your eagerness; do not do so again.
حَدَّثَنَا مُوسَى بْنُ إِسْمَاعِيلَ، قَالَ حَدَّثَنَا هَمَّامٌ، عَنِ الأَعْلَمِ ـ وَهْوَ زِيَادٌ ـ عَنِ الْحَسَنِ، عَنْ أَبِي بَكْرَةَ، أَنَّهُ انْتَهَى إِلَى النَّبِيِّ صلى الله عليه وسلم وَهْوَ رَاكِعٌ، فَرَكَعَ قَبْلَ أَنْ يَصِلَ إِلَى الصَّفِّ، فَذَكَرَ ذَلِكَ لِلنَّبِيِّ صلى الله عليه وسلم فَقَالَ " زَادَكَ اللَّهُ حِرْصًا وَلاَ تَعُدْ ".
