O you who believe! be careful of (your duty to) Allah and be with the true ones. 119 It was not proper for the people of Madinah and those desert Arabs around them to hold back from following God's Messenger, and to prefer their own lives to his life. This is because whenever they suffer from thirst or weariness or hunger for God's cause, and whenever they take any step which provokes those who deny the truth, or inflicts any loss upon the enemy, it shall be counted as a good deed in the sight of God, God will not deny the righteous their reward, 120 And whatever they spend, small or great, or any valley they cross – it is all recorded for them, so that Allah may reward them for their best deeds. 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
