When you travel in the land there is no sin if you curtail your service of prayer if you fear the unbelievers may harass you, for indeed your open enemies are the infidels. 101 Thus, when thou art among the believers and about to lead them in prayer, let [only] part of them stand up with thee, retaining their arms. Then, after they have finished their prayer, let them provide you cover while another group, who have not yet prayed, shall come forward and pray with thee, being fully prepared against danger and retaining their arms: (for) those who are bent on denying the truth would love to see you oblivious of your arms and your equipment, so that they might fall upon you in a surprise attack. But it shall not be wrong for you to lay down your arms [while you pray] if you are troubled by rain or if you are ill; but [always] be fully prepared against danger. Verily, God has readied shameful suffering for all who deny the truth! 102 When you complete your prayer, remember God all the time while standing, sitting, or reclining. When you are safe, say your prayers properly. It is a constant duty of the believers. 103 And be not weak hearted in pursuit of the enemy; if you suffer pain, then surely they (too) suffer pain as you suffer pain, and you hope from Allah what they do not hope; and Allah is Knowing, Wise. 104
