Desirability of Supplications during the Journey
980. Abu Hurairah (May Allah be pleased with him) reported: The Messenger of Allah (PBUH) said, "Three supplications are answered without doubt. The supplication of the oppressed, the supplication of the traveller, and the supplication of the parent for his son.''
[At-Tirmidhi and Abu Dawud].
Commentary: This Hadith mentions two dimensions of supplications. First, the supplication of an oppressed person will be in favour of the one who will come to his help and redress his complaint, whereas the oppressor will be hit by his supplication. Second, Allah also answers the father's supplication for his disobedient and impudent son; and the mother's supplication is even more effective than that of the father's because, as compared to him, she has more rights over them. Man should, therefore, restrain himself from disobeying parents, so that he may escape in both cases the supplication which is not rejected by Allah.
