The unification of the imam nor the follower is not a condition, just like prayers that are not combined. His statement that the imam and the follower are those through whom the combination is completed is incorrect, for it is permissible for the patient and the traveler to combine individually, and in the case of rain according to one of the two views. Even if we say that combining during rain is not valid except in a congregation, then that through which the combination is completed is the congregation, not the specific imam or the follower, and the congregation has not been compromised. According to what we have mentioned, if a follower follows an imam who does not intend to combine, but the follower intends it, then when the imam delivers the taslim, the follower prays the second, it is permissible; for we have permitted him to diverge from his imam in a single prayer due to an excuse, so it is even more appropriate in two prayers. Moreover, their intentions did not differ in the first prayer; he only intended to perform an action [that leads to] another, so it is similar to if a traveler intends during the first prayer to complete the second. Likewise, if a traveler prays behind residents and intends to combine, then when he has prayed the first with them, he stands and prays the second, it is permissible according to this view. Likewise, if he performs one of the two combined prayers alone, then a congregation arrives performing the second, and he leads them in it, or prays as a follower with them, it is permissible. Ibn Aqil's statement implies that none of this is permissible.

274 - Issue: He said: "If one forgets a prayer from a time of residency and remembers it while traveling, or a prayer from a time of travel and remembers it while in residency, he shall pray in both cases (1) a prayer of residency."

Ahmad, may Allah have mercy on him, specified these two issues in the narration of Abu Dawud and al-Athram. He said in the narration of al-Athram: As for the resident who remembers it while traveling, that is by consensus; he prays four [rak'ahs]. If he forgets it while traveling and remembers it while in residency, he prays four [rak'ahs] as a precaution, for it only became incumbent upon him at that moment. Abu Abdullah, may Allah have mercy on him, went by the apparent meaning of the hadith: "Let him pray it when he remembers it" (2). As for when he forgets a prayer of residency and remembers it while traveling, he must complete it
