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 Why, surely to God belongs whatsoever is in the heavens and the earth; He ever knows what state you are upon; and the day when they shall be returned to Him, then He will tell them of what they did; and God knows everything. 64
