O you who believe! Be afraid of Allah, and be with those who are true (in words and deeds). 119 It did not beseem the people of Medina and those round about them of the dwellers of the desert to remain behind the Apostle of Allah, nor should they desire (anything) for themselves in preference to him; this is because there afflicts them not thirst or fatigue or hunger in Allah's way, nor do they tread a path which enrages the unbelievers, nor do they attain from the enemy what they attain, but a good work is written down to them on account of it; surely Allah does not waste the reward of the doers of good; 120 Also, they would not have spent anything, great or small, for the cause of God or travel through a valley without God decreeing a reward for them far better than whatever they had done. 121 ۞ And it is not for the believers to march forth all together. So why should not a band from each party of them march forth so that they may gain understanding in religion and that when they come back unto them, haply they might warn their people when they come back unto them, haply they may beware! 122
