Doubt after the time of Namaz has passed

1189. If a person doubts, after the time for prayers has already passed, as to whether he has offered the prayers or not, or if he suspects that he may not have offered it, it is not necessary for him to offer that prayers. If, however, he doubts before the expiry of the time for that prayers, as to whether or not he has offered it, he should offer it, even if he has a feeling that he might have done so.
