There is no harm in your eating together or separately. But when you enter the houses, salute the inmates with a greeting in the name of God, invoking blessings and good health. That is how God explains things to you clearly so that you may understand. They alone are true believers who believe in God and His Apostle, and when they are with him on a matter of common concern, do not depart without obtaining his leave. Surely those who ask leave of you are the ones who believe in God and His Apostle. Therefore when they ask leave of you for personal business give leave to those you please, and seek God's forgiveness for them. Surely God is forgiving and kind. 62 Make not the calling of the messenger among you as your calling one of another. Allah knoweth those of you who steal away, hiding themselves. And let those who conspire to evade orders beware lest grief or painful punishment befall them. 63 The heavens and the earth, certainly, belong to God. He surely knows all about you in this life. On the day when you return to Him, He will tell you all about whatever you have done. God has the knowledge of all things. 64
