Is the prayer valid without bowing and prostrating in severe congestion?

Question : This questioner asks and says: Honorable Shaykh, due to the severe congestion in the night prayer, some people prayed the obligatory and voluntary prayers while standing. Is their prayer valid?

Answer : Yes, if the congestion is severe and a person cannot find a place to prostrate, I think bowing is not difficult, or is it? Hmm? Is even bowing difficult?
Well, if bowing becomes difficult, he nods while standing. For prostration, he sits and nods. Some scholars said that he should prostrate on the back of a person in case of tightness, but the first option is better: that he sits and nods. Because prostrating on a person’s back is an action upon his person without his permission, and prostrating on him is problematic. Also, if he prostrates on him, it may cause harm to him, if the one being prostrated upon is thin and the one prostrating is, God willing, heavy. Yes. Hmm. He may be affected.
Thirdly, perhaps the one being prostrated upon gets up in defiance of the prostrator. Yes, in any case, the matter is broad, praise be to Allah. He sits and nods for the prostration. As long as it has been said about it, it is better. Other scholars say he should wait until the people rise from prostration, and when the people rise from prostration, the space opens up, so he prostrates after the imam’s prostration. His delay behind the imam is due to an excuse. But the middle opinion is the middle one, God willing, which is that he sits and nods for the prostration. Yes.
