O you who believe! be careful of (your duty to) Allah and be with the true ones. 119 It does not behove the people of the [Prophet's] City and the bedouin [who live] around them to hold back from following God's Apostle, or to care for their own selves more than for him - for, whenever they suffer from thirst or weariness or hunger in God's cause, and whenever they take any step which confounds those who deny the truth, and whenever there comes to them from the enemy whatever may be destined for them - [whenever anything thereof comes to pass,] a good deed is recorded in their favour. Verily, God does not fail to requite the doers of good! 120 Nor do they spend anything (in Allah's Cause) - small or great - nor cross a valley, but is written to their credit, that Allah may recompense them with the best of what they used to do (i.e. Allah will reward their good deeds according to the reward of their best deeds which they did in the most perfect manner). 121 ۞ And it is not for the believers to go forth [to battle] all at once. For there should separate from every division of them a group [remaining] to obtain understanding in the religion and warn their people when they return to them that they might be cautious. 122
