Bismillah Walhamdulillah Was Salaatu Was Salaam ‘ala Rasulillah
Narrated ‘Abdullah bin ‘Amr (Radi-Allahu ‘anhu):
A man came to the Prophet (Sallallahu ‘Alaihi Wa Sallam) asking his permission to take part in Jihad. The Prophet asked him, “Are your parents alive?” He replied in the affirmative. The Prophet (Sallallahu ‘Alaihi Wa Sallam) said to him, “Then exert yourself in their service.”
