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!
