Issue No.1104- If a person doubts whether he has done an act which causes sajdah al-sahw or not, it is not necessary for him to perform it. However, if he doubts whether it is obligatory to perform sajdah al-sahw once or twice, it will be sufficient if he performs only once.
Issue No.1108- With respect to the qaḍā of the Forgotten sajdah and tashahhud, all the conditions of prayer, such as ṭahārah, qiblah, and all other conditions are required, and one should perform the qaḍā immediately after the prayer. Also, when performing the qaḍā of tashahhud, one should perform the salām afterwards.
Issue No.1109- If a person forgets one sajdah and the tashahhud, the obligatory precaution is to first offer the qaḍā of the one he forgot first. If he does not know which one he forgot first, he should, as an obligatory precaution, perform one sajdah, and then a tashahhud, and then perform another sajdah to make sure that he has performed the qaḍā of the sajdah and tashahhud in the order they were missed.
Issue No.1110- If a person performs an act after prayer that disturbs the form of prayer or invalidates the prayer (like turning his back towards the qiblah), he should perform the qaḍā of the sajdah and tashahhud and, as an obligatory precaution, repeat the prayer. If he has done an act that makes sajdah al-sahw obligatory upon him, he should, as an obligatory precaution, perform sajdah al-sahw after performing the qaḍā of sajdah or tashahhud.
Issue No.1111- If one doubts whether or not he has forgotten a sajdah or tashahhud, it is not obligatory to perform its qaḍā, but if he knows that he has forgotten one of them but he does not know which one, he should offer qaḍā for both of them and there is no problem in offering either of them first.
Issue No.1112- If a person has to offer qaḍā of a sajdah or a tashahhud as well as the sajdah al-sahw, he should after prayer offer the qaḍā of sajdah or tashahhud first, and then perform the sajdah al-sahw.
Issue No.1113- If one doubts whether or not he has offered the qaḍā of the forgotten sajdah or tashahhud that was an obligation upon him after prayer, he should perform the qaḍā of the sajdah or tashahhud if the prayer time has not lapsed, and if the time has lapsed, he should, as an obligatory precaution, offer its qaḍā and his prayer will be correct.
Issue No.1114-In order to perform the qaḍā of the forgotten sajdah or tashahhud, One should make the intention after the prayer and then he should perform the qaḍā of sajdah or tashahhud without saying “Allahu Akbar” or anything else. Thereafter, he should, as an obligatory precaution, perform sajdah al-sahw.
Issue No.1117- If a person realises before the salām of prayer that he has not offered one rak‘at or more of the final rak‘ats of prayer, he should perform the rak‘at which had been forgotten, and his prayer is correct. However, if he realises this after the salām of prayer, and he has done an act which doing it intentionally or inadvertently invalidates the prayer (e.g. turning one's back towards the qiblah), the prayer will be void. In case however, he has not performed such an act, he should immediately perform the forgotten rak‘ats and the prayer will be valid, and he should, as an obligatory precaution, perform sajdah al-sahw for the undue salām.

Issue No.1118- If a person realises that he has offered the prayer before the prescribed time or he has performed it having his back towards the qiblah, he should repeat the prayer, or perform its qaḍā in case the time has lapsed. However, if he has offered prayer towards the right or left of the qiblah inadvertently, the prayer will not be void.
