O you who have believed, fear Allah and be with those who are true. 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 Nor do they spend an expenditure, small or large, or cross a valley but that it is registered for them that Allah may reward them for the best of what they were doing. 121 ۞ It was not necessary for the believers to go forth all together (to receive religious instruction), but why did not a party of them go forth that they may grow in religious understanding, and that they may warn their people when they return to them, so that they may avoid (erroneous attitudes)? 122
