The Ruling on the Sitting of Rest and Closing the Gaps in the Rows

Question:
He asks: Is the sitting of rest part of the Sunnah? And what is the ruling on closing the gaps in the rows?

Answer:
The correct view is that the sitting of rest is not a recommended practice (sunnah), but rather it is permissible for those who need it, such as the elderly or the sick. As for the strong person, he does not sit for rest because he does not need it. The Prophet (peace and blessings be upon him) did not do it when he was strong; he only did it when the prayer became heavy for him (peace and blessings be upon him). This is the sitting of rest. And what is the rest of the question?

Question:
He says: Closing the gaps in the rows.

Answer:
Closing the gaps in the rows is obligatory, and no gap should remain in the rows through which Satan can pass. The Prophet (peace and blessings be upon him) commanded to align the rows, straighten them, and take care of them, because this is part of the completion of the prayer. Yes.
