Doubts about an act whose time of performance has passed

1177. If a person doubts while offering prayers as to whether or not he has performed a particular obligatory act, like, if he doubts whether or not he has recited Surah al-Hamd, and if he has engaged himself in the next act, which he would not have intentionally performed in a normal circumstance, like reading the next Surah, he should ignore the doubt. But in a situation other than this, he should perform the act about which he doubts.

1178. If a person doubts while reciting a verse, whether or not he has recited the preceding verse, or doubts while reciting the end part of a verse, whether or not he has recited its beginning, he should ignore his doubt.

1179. If a person doubts after Ruku or Sajdah, whether or not he has performed its obligatory parts, like Zikr and steadiness of the body, he should ignore his doubt.

1180. If, while going into Sajdah, a person doubts whether or not he has performed Ruku, or if he doubts whether he stood up after Ruku or not, he should ignore the doubt.

1181. If a person doubts while rising to stand, whether or not he has performed Sajdah or tashahhud, he should ignore the doubt.

1182. If a person, who is offering prayers sitting or lying, doubts at the time of reciting Surah al-Hamd or Tasbihat Arba'ah, whether or not he has performed Sajdah or tashahhud, he should ignore his doubt. And if the doubt occurs before reciting Surah al-Hamd or Tasbihat Arba'ah , he should perform them.

1183. If a person doubts whether or not he has performed one of the Rukn of prayers, and if he has not yet engaged himself in the next act, he should perform it. For example, if he doubts before reciting tashahhud, whether or not he has performed two Sajdah, he should perform them. And if he remembers later that he had already performed that Rukn, as an obligatory precaution,his prayers will become void because of additional Rukn.

1184. If a person doubts whether or not he has performed an act which is not a Rukn of namaz, and if he has not engaged himself in the following act, he should perform it. For example, if he doubts before reciting the other Surah, whether or not he has recited Surah al-Hamd, he should recite Hamd. And if he remembers after reciting Hamd that he had already recited it, his prayers will be in order, because a Rukn has not been added.

1185. If a person doubts whether or not he has performed a Rukn, like, while in tashahhud, he doubts whether or not he has performed two Sajdah, and ignores his doubt, but remembers later that he had actually not performed that Rukn, he should perform it if he has not entered into the next Rukn.
However, if he has engaged himself in the next Rukn, his prayer is void. For example, if he remembers before Ruku of the next Rak'at, that he had not performed two Sajdah, he should perform them, and if he remembers this during Ruku or thereafter, his prayers are void.

1186. If a person doubts whether or not he has performed an act which is not a Rukn, and if he is engaged in the next act, he should ignore his doubt. For example, if he doubts while reciting the other Surah, whether or not he has recited Surah al-Hamd, he should ignore his doubt.
And if he remembers later that he had actually not performed that act, he should perform it, if he has not entered into the next Rukn, and if he has entered the next Rukn, his prayers are in order. Based on this, if he remembers in qunut that he has not recited Surah al-Hamd he should recite it, and if he remembers it in Ruku, his prayers are in order.

1187. If a person doubts whether or not he has said Salam of prayers when he is engaged in supplications or other namaz, or when the form of namaz has already changed, he should ignore his doubt. And if he doubts before these acts, he should say Salam. And if he doubts at any stage, whether he recited the Salam correctly or not, he should ignore that doubt.
