I reached the Prophet ﷺ in the mosque while he was bowing in prayer and I too bowed before joining the row mentioned it to the Prophet ﷺ and he said to me, "May Allah increase your love for the good. But do not repeat it again (bowing in that way).
أَنَّهُ انْتَهَى إِلَى النَّبِيِّ ﷺ وَهْوَ رَاكِعٌ فَرَكَعَ قَبْلَ أَنْ يَصِلَ إِلَى الصَّفِّ فَذَكَرَ ذَلِكَ لِلنَّبِيِّ ﷺ فَقَالَ زَادَكَ اللَّهُ حِرْصًا وَلاَ تَعُدْ
Abu Bakrah said that he came to the mosque when the prophet ﷺ was bowing. So I bowed outside the row (before joining it). The prophet ﷺ said; May Allah increase your eagerness! But do not do it again.
أَنَّهُ دَخَلَ الْمَسْجِدَ وَنَبِيُّ اللَّهِ ﷺ رَاكِعٌ قَالَ فَرَكَعْتُ دُونَ الصَّفِّ فَقَالَ النَّبِيُّ ﷺ زَادَكَ اللَّهُ حِرْصًا وَلاَ تَعُدْ
Abu Bakrah said that he came to the mosque when the prophet ﷺ was bowing. So I bowed outside the row (before joining it). The prophet ﷺ said; May Allah increase your eagerness! But do not do it again. (Using translation from Abū Dāʾūd 683)
أَنَّهُ دَخَلَ الْمَسْجِدَ وَالنَّبِيُّ ﷺ رَاكِعٌ فَرَكَعَ قَبْلَ أَنْ يَصِلَ إِلَى الصَّفِّ فَقَالَ لَهُ النَّبِيُّ ﷺ زَادَكَ اللهُ حِرْصًا وَلَا تَعُدْ
[Machine] Abu Bakrah entered the mosque and the Imam was bowing. Abu Bakrah also bowed before reaching the row. The Prophet ﷺ said to him, "May Allah increase your eagerness, but do not count (the rows)."
أَنَّ أَبَا بَكْرَةَ دَخَلَ الْمَسْجِدَ وَالْإِمَامُ رَاكِعٌ فَرَكَعَ قَبْلَ أَنْ يَصِلَ إِلَى الصَّفِّ فَقَالَ لَهُ النَّبِيُّ ﷺ زَادَكَ اللهُ حِرْصًا وَلَا تَعُدْ
