Sajdah-e-Sahw
Q: Is the sajdah sahw only waajib in those instances when it is allowed to pray? For example if one is praying Fajr and after the salaam the sun does rise, does he need to do sajdah sahw or his he absolved ? If not does he later need to repeat the Fajr (because he did not do sajdah sahw)?
If one praying Asr and after he makes salaam the redness of the horizon is visible, does he need to do sajdah sahw or is he absolved ? If not does he later need to repeat the Asr ?
