Questioner: Shaikh, a praying person comes late to the congregational prayer and he missed three raka’at of dhuhr, then the Imam ends the prayer. What is the amount [of steps] he can walk in order to take a sutrah?
Shaikh: He takes [an amount of] steps such that if he was seen, no one will say “he is not praying”.
Questioner: And if he finds someone who says that he he is not praying, [does that mean] this is a lot of walking?
Shaikh: We said he does not walk. He does not take [an amount of] steps which if someone outside of the prayer saw him, he would think that he is not praying because a lot of actions is what nullifies the prayer”
