O ye who believe! Fear Allah and be with those who are true (in word and deed). 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 they expend not an expending, small or great, or transverse a vale, but it is written down unto them, so that Allah may recompense them with the best for that which they have been working. 121 ۞ It is not possible for all believers to go out (to fight). So a part of each section (of the population) should go (to fight) in order that the others may acquire understanding of law and divinity, and warn their companions on return so that they may take heed for themselves. 122
