Prayer: In Nāfilah Prayers, Should I Ignore Doubts About Actions Like One or Two Prostrations?
English:
Question #515:
Should a person pay heed to doubts that occur in nāfilah prayers (other than the doubt concerning the number of performed rak‘ahs)? For example, he is unaware whether he has done one prostration or two.
Answer #515:
The rule of doubts in the words and deeds of nāfilah prayer is the same as those of obligatory prayers, i.e. the doubt is heeded if its pertinent place has not passed, and is ignored after that.
