O you who believe! be careful of (your duty to) Allah and be with the true 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 ۞ It is not right that all the believers should go out [in time of war] all together. Why, then, does not a party from every group come to [the Prophet] in order to acquire a deeper knowledge of religion and to warn their people, so that they can guard themselves against evil? 122
