Number 7132:
The son of Abu Said al-Khudri reported on the authority of his father
that Allah’s Messenger (sallallahu alayhi wa sallam) said:
When one of you yawns while engaged in prayer, he should try to
restrain so far as it lies in his power, since it is the Satan that
enter therein.
(Sahih Muslim)
“I put my trust in Allah, my Lord and your Lord! There is not a moving creature, but He has a grasp of its forelock. Verily, my Lord is on the straight path. (The truth)”
(11:55-56)
