Entering the prayer with the imam while he is bowing is preferable to the opening takbir
Machine translationRead the Arabic original
Q: If you enter the mosque and find the imam bowing or prostrating, am I allowed to perform the opening takbir in this case? Or is the imam’s opening takbir sufficient for me?
A: If you find him bowing or prostrating, say the takbir and enter the prayer with him; there is no need for the opening takbir.
