‘Abdallah b. ‘Amr told that a man came to God’s Messenger and asked his permission to take part in jihad. He asked him if his parents were still alive, and when he replied that they were, he told him to exert himself* on their behalf.
*The point is not so clear in English as in Arabic. Jihad, while being the word for fighting against infidels, also means to strive or to exert oneself in general. The man wished to take part in jihad, and when the Prophet heard that his parents were still alive he said fa-fihima fa-jahid (exert yourself on their behalf.)
(Bukhari and Muslim.) A version has, “Return to your parents and look after them well.”
Anas told that when God’s Messenger returned from the expedition to Tabuk and approached Medina he said, “In Medina there are people who did not fail to be with you wherever you went and whatever wadi you crossed.” A version has, “Who have not failed to share your reward.” On their expressing surprise that that should be true when they were still in Medina, he said, “While they are still in Medina, being kept back by a valid excuse.”
Bukhari transmitted it, and Muslim transmitted it on Jabir’s authority.
Ibn ‘Abbas reported the Prophet as saying on the day of the Conquest of Mecca, “There is no emigration after the Conquest, but only jihad and some good intention; so when you are summoned to fight, go forth.”
‘Imran b Husain reported God’s Messenger as saying, “A section, of my people will continue to fight for the right and overcome their opponents till the last of them fight with the antichrist."
