Q 1: What is the ruling on
performing Salah (Prayer) alone behind a row
when there is no gap in the row? Should one perform the Salah standing alone behind the row or pull someone back from the row in front?
A:
If someone joins Salah and the row is full, they should try to find a place in the row. If it is not possible, they should stand to the right of the Imam. If this is also not possible, they should wait until someone comes to form a new row with them. It is not permissible to pray alone behind the row, because the Prophet (peace be upon him) said,
“There is no Salah for the one who prays alone behind the row.”
The Messenger of Allah (peace be upon him) saw a man performing Salah alone behind the row and ordered him to repeat the Salah.
