It is most appropriate to supplicate for the early reappearance of Imam-e-Asr (as) at such moments for the following reasons:

First: It is the cause of his prayers (in our favor) as already mentioned.

Second: It is the cause of the supplications of the angels because they pray for one who prays for an absent believer and their prayers are accepted, Inshallah.

Third: His (aj) command, “And pray more for the hastening of the reappearance. For surely, this is your salvation.”

Fourth: Supplication is a medium to reach unto him (aj) and he, in turn, is the best medium of safety from difficulties, trials and tribulations.
