Question: 

I have noticed that when a brother wants to make a new row during Salaah, he starts from the middle. Is this permissible?

Answer:

Lajnatu Daaimah said:

“The first row should begin in the prayer from behind the Imam then onwards to the right and to the left and it doesn’t begin from the far right”

The Reference: Fataawa Ulemaa al-Haraam (239), print Daarul Baseerah.
