What is prescribed for the one who joins the prayer late to do if he catches the imam in bowing

Q: If the one who joins the prayer late catches the imam in bowing, what is prescribed for him at that time? And is it a condition for the ruling that he caught the rak'ah that he say: Subhan Rabbi al-Azim (Glory be to my Lord, the Great) before the imam rises?

A: If the ma'mum catches the imam in bowing, the rak'ah is valid for him, even if the ma'mum does not say the tasbih until after the imam has risen; due to the generality of his statement (peace and blessings be upon him): It was narrated by Muslim in his Sahih.
And it is known that the rak'ah is caught by catching the ruku'; for al-Bukhari narrated in his Sahih from Abu Bakrah al-Thaqafi (may Allah be pleased with him) that he came to the mosque one day and the Prophet (peace and blessings be upon him) was in bowing, so he bowed before the row, then entered the row. When the Prophet (peace and blessings be upon him) finished the prayer, he said to him (peace and blessings be upon him): And he did not order him to make up the rak'ah, but only forbade him from returning to bowing before the row. So the one who joins the prayer late should not hasten to bow until he enters the row.
