O People who Believe! Fear Allah, and be with the truthful. 119 It does not behove the people of the [Prophet's] City and the bedouin [who live] around them to hold back from following God's Apostle, or to care for their own selves more than for him - for, whenever they suffer from thirst or weariness or hunger in God's cause, and whenever they take any step which confounds those who deny the truth, and whenever there comes to them from the enemy whatever may be destined for them - [whenever anything thereof comes to pass,] a good deed is recorded in their favour. Verily, God does not fail to requite the doers of good! 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 ۞ With all this, it is not desirable that all of the believers take the field [in time of war]. From within every group in their midst, some shall refrain from going forth to war, and shall devote themselves [instead] to acquiring a deeper knowledge of the Faith and [thus be able to] teach their home-coming brethren, so that these [too] might guard themselves against evil. 122
