O ye who believe! Be careful of your duty to Allah, and be with the truthful. 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 expend any sum, small or great, nor do they traverse any valley, but it is written to their account, that God may recompense them the best of what they were doing. 121 ۞ It is not for the believers to go forth totally; but why should not a party of every section of them go forth, to become learned in religion, and to warn their people when they return to them, that haply they may beware? 122
