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 Do not treat being called by the Messenger like being called by one another. God knows those of you who slip away on some pretext. Let those who go against his order beware lest some affliction befall them or they receive a painful punishment. 63 Does not everything in the heavens and the earth belong to God? He surely knows what state you are in; and on the day they go back to Him. He will tell them what they used to do, for God has knowledge of everything. 64
