O ye who believe! Fear Allah and be with those who are true (in word and deed). 119 It was not worthy of the people of Madina, and the Arabs of the desert around them, to abandon the Prophet of God, and to care more for themselves than for him; for there is no hardship or thirst or hunger that they know in the service of God, and no place they walk on where walking provokes the unbelievers, and no harm they receive from the enemy, but is put down as a good deed in their favour. Surely God does not let the recompense of those who do good to go waste. 120 and whenever they spend anything [for the sake of God], be it little or much, and whenever they traverse the land [in God's cause] -- it is recorded to their credit, and God will grant them the best reward for all that they have been doing. 121 ۞ It is not possible for all believers to go out (to fight). So a part of each section (of the population) should go (to fight) in order that the others may acquire understanding of law and divinity, and warn their companions on return so that they may take heed for themselves. 122
