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 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 ۞ It is not for the believers to go forth totally; but why should not a party of every section of them go forth, to become learned in religion, and to warn their people when they return to them, that haply they may beware? 122
