A BENEFIT
=========
If the Ma'mom has forgot two times, one needs Sujuoud Al Sahw before Al Tasleem and one after it, it is preferable to perform it before Al Tasleem. Al Othaimeen.
If he recites Quraan while Kneeling or prostrating unintentionally, is it obligatory to perform Sujuoud Al Sahw or is it sunnah?
Most of the scholars said it is not obligatory.
Mistakes of common people in prayer
=======================
Some people say "subhan he who doesn't forget or sleep" in Sujuoud Al Sahw. This saying has no evidence is Al Share (religion).
The prophet, peace be upon him, didn't say anything in Sujuoud Al Sahw, but he said the prayer usual zikr.
Saying "subhan he who doesn't forget or sleep", wasn't said by the prophet or any of his companions, and is not in sunnah. This was said by one of the mystics, he saw it in his dream, so we don't have to say it.. we should follow the right sunnah books.
Some leave Sujuoud Al Sahw, which is after Al Tasleem , if he forgets it .
Some jurists said, if there is along period of time, he doesn't perform Sujuoud Al Sahw .
Others said one should perform it as long as he still in the Mosque .
Others said he doesn't have to do it in both cases.
Ahmed said that he should do it if he left the Mosque and became away from it.
Determining time or place is not in share (religion).. Sheikh Al Islam said this also
