Believers, always be well prepared and on your guard. March in small groups or all together. 71 And behold, there are indeed among you such as would lag behind, and then, if calamity befalls you, say: "God has bestowed His favour upon me in that I did not accompany them." 72 But if good fortune comes to you from Allah, they would be sure to say - as if there had never been Ties of affection between you and them - "Oh! I wish I had been with them; a fine thing should I then have made of it!" 73 ۞ Let those (believers) who sell the life of this world for the Hereafter fight in the Cause of Allah, and whoso fights in the Cause of Allah, and is killed or gets victory, We shall bestow on him a great reward. 74 And what is the matter with you, that you should not fight in Allah’s cause and for the feeble men, and women, and children, who invoke, “Our Lord! Liberate us from this town, the people of which are unjust; and give us a protector from Yourself; and give us a supporter from Yourself.” (Allah has created many supporters for the believers.) 75 The believers fight for Allah’s cause; and the disbelievers fight for the devil’s cause – so fight against the friends of the devil; undoubtedly the devil’s conspiracy is weak. 76
