4:78Wherever you may be, death will catch up with you, even if you were in fortified towers. When a good fortune comes their way, they say, “This is from God.” But when a misfortune befalls them, they say, “This is from you.” Say, “All is from God.” So what is the matter with these people, that they hardly understand a thing?

4:102When you are among them, and you stand to lead them in prayer, let a group of them stand with you, and let them hold their weapons. Then, when they have done their prostrations, let them withdraw to the rear, and let another group, that have not prayed yet, come forward and pray with you; and let them take their precautions and their weapons. Those who disbelieve would like you to neglect your weapons and your equipment, so they can attack you in a single assault. You commit no error, if you are hampered by rain or are sick, by putting down your weapons; but take precautions. Indeed, God has prepared for the disbelievers a demeaning punishment.

4:103When you have completed the prayer, remember God, standing, or sitting, or on your sides. And when you feel secure, perform the prayer. The prayer is obligatory for believers at specific times.

4:135O you who believe! Stand firmly for justice, as witnesses to God, even if against yourselves, or your parents, or your relatives. Whether one is rich or poor, God takes care of both. So do not follow your desires, lest you swerve. If you deviate, or turn away—then God is Aware of what you do.

4:142The hypocrites try to deceive God, but He is deceiving them. And when they stand for prayer, they stand lazily, showing off in front of people, and remembering God only a little.
