When you are on a journey, it is no sin to shorten your prayers if you are afraid of the mischief of the unbelievers. The unbelievers have always been your sworn enemies 101 And when you (O dear Prophet Mohammed – peace and blessings be upon him) are among them and lead them in prayer, only a group of them should be with you, and they must keep their weapons with them; so when they have performed their prostrations they should move away behind you; and the other group that had not prayed, must come and offer prayers in your leadership, keeping their guard and weapons with them; the disbelievers wish that you neglect your arms and your means so they may overpower you with a single attack; it is no sin for you to lay aside your arms due to rain or if you are sick; and keep your guard; undoubtedly Allah has kept prepared a disgraceful punishment for the disbelievers. 102 So when you have offered your prayers remember Allah while standing, sitting and reclining; and when you feel secure, offer prayers in the usual manner; indeed prayers are a time bound obligatory duty upon the Muslims. 103 And slacken not in following up the enemy: If ye are suffering hardships, they are suffering similar hardships; but ye have Hope from Allah, while they have none. And Allah is full of knowledge and wisdom. 104
