The questioner : Yes. Honorable Shaykh, may Allah reward you, do you not see that it is a necessary consequence of the Companions sleeping in the mosque that they pass gas?
The Shaykh : Yes, we seek help from Allah, but did they sleep in order to emit foul odors?
The questioner : No, no.
The Shaykh : That is settled, as long as they did not sleep for that purpose.
The questioner : And so it is with the one in i'tikaf (spiritual retreat in the mosque).
The Shaykh : He did not perform i'tikaf. There is a difference between a person who controls his passing of gas while awake and a person who is sleeping. In the case of the sleeper, the act is done to him, and there is no problem. I say it does not apply to us. Yes.
