O People who Believe! Fear Allah, and be with the truthful. 119 It was not for the people of Madina and those around them of the desert dwellers that they should lay behind the apostle of Allah, nor that they should prefer themselves before him. That is because there afflicteth them not thirst or fatigue or hunger in the way of Allah or they tread a place trodden on enraging the infidels, nor they attain an attainment from the enemy, but a good deed is thereby written down unto them. Verily Allah wasteth not the hire of the well-doers. 120 And whenever they spend anything [for the sake of God,] be it little or much, and whenever they move on earth [in God's cause] - it is recorded in their favour, 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
