Hadith 423
Sayyiduna Abdullah bin Amr (may Allah be pleased with him) narrates: A man came to the service of the Prophet Muhammad (peace be upon him) to pledge allegiance for migration. He accepted Islam, and then said: I have left my parents weeping. The Prophet Muhammad (peace be upon him) said: Go back to them, and make them laugh just as you made them weep. The Prophet Muhammad (peace be upon him) did not accept his request to go with him (for jihad).
