Abu Bakrah came when the apostle of Allah ﷺ was bowing. So he bowed without the row (before joining it). He then went to the row. When the prophet ﷺ finished his prayer, he said: which of your bowed without the row, and then went to the row? Abu Bakrah said; it was i. the prophet ﷺ said: May Allah increase your eagerness ! but do not do it again. (Using translation from Abū Dāʾūd 684)
أَنَّهُ جَاءَ وَالنَّاسُ رُكُوعٌ فَرَكَعَ دُونَ الصَّفِّ ثُمَّ مَشَى إِلَى الصَّفِّ فَلَمَّا قَضَى رَسُولُ اللهِ ﷺ صَلَاتَهُ قَالَ أَيُّكُمُ الَّذِي رَكَعَ دُونَ الصَّفِّ ثُمَّ مَشَى إِلَى الصَّفِّ؟ قَالَ أَبُو بَكَرَةَ أَنَا يَا رَسُولَ اللهِ قَالَ زَادَكَ اللهُ حِرْصًا وَلَا تَعُدْ لَفْظُ حَدِيثِ الْمُقْرِئِ وَفِي حَدِيثِ الرُّوذْبَارِيِّ أَنَّ أَبَا بَكَرَةَ جَاءَ وَرَسُولُ اللهِ ﷺ رَاكِعٌ وَالْبَاقِي مِثْلُهُ
