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 O Believers, do not consider the summoning by the Messenger like the summoning among you by one another. Allah knows well those of you who steal away, concealing themselves behind others. Let those who disobey the order of the Messenger beware lest they should be involved in some affliction, or are visited by a woeful scourge. 63 Oh, verily, unto God belongs all that is in the heavens and on earth: well does He know where you stand and at what you aim! And one Day, all [who have ever lived] will be brought back unto Him, and then He will make them [truly] understand all that they were doing [in life]: for, God has full knowledge of everything. 64
