He -asws said...
He -asws said: ‘He should do Sajdah when he hears something from the Mighty four (Verses), then he should gesture and complete his Salat, except if he happens to be in an obligatory Salat, he should indicate with his head gestures’’.
Muhammad Bin Yahya, from Ahmad Bin Muhammad, from Al Husayn Bin Saeed, from Al Qasim Bin Muhammad, from Ali Bin Abu Hamza, from Abu Baseer who said, ‘He -asws said: ‘When something from the four determined Verses (32:15, or 41:38, or 53:62 or 96:19) is recited, so perform Sajdah , and even though you might be without an ablution, and even if you were with a sexual impurity, and even if you were a woman not praying Salāt (due to menstruation etc.); and (as for as) the rest of the Quran, you are with the choice therein, if you so desire to, you perform Sajdah , and if you so desire to, you do not perform Sajdah ’.
Ali Bin Ibrahim, from Muhammad Bin Isa Bin Ubeyd, from Yunus Bin Abdul Rahman, from Abdullah Bin Sinan who said, ‘I asked Abu Abdullah -asws about a man who heard the Sajdah (Verse) being recited. He -asws said: ‘He should not perform Sajdah unless if he happens to be (deliberately) listen to its recitation, listening intently to it, or he is praying a Salāt with his Salāt .
So if he happens to be praying Salāt in a corner and you are praying Salāt in another corner, so you do not perform Sajdah to what you hear’.
