What advice did the Prophet Muhammad (saw) give to the man who had enlisted in the army and whose wife was leaving for Hajj?
 Narrated Ibn `Abbas:                     A man came to the Prophet and said, "O Allah's Apostle! I have enlisted in the army for such-andsuch Ghazwa, and my wife is leaving for Hajj." Allah's Apostle said, "Go back and perform Hajj with your wife."
