Believers, have fear of God and always be friends with the truthful ones. 119 It was not becoming of the people of Al-Madinah and the bedouins of the neighbourhood to remain behind Allah's Messenger (Muhammad SAW when fighting in Allah's Cause) and (it was not becoming of them) to prefer their own lives to his life. That is because they suffer neither thirst nor fatigue, nor hunger in the Cause of Allah, nor they take any step to raise the anger of disbelievers nor inflict any injury upon an enemy but is written to their credit as a deed of righteousness. Surely, Allah wastes not the reward of the Muhsinun 120 and whenever they spend anything [for the sake of God], be it little or much, and whenever they traverse the land [in God's cause] -- it is recorded to their credit, and God will grant them the best reward for all that they have been doing. 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
