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 Place not the apostle's calling among you on the same footing as your calling of each other. Of a surety Allah knoweth those who slip away privately; let therefore those who oppose His commandment beware lest there befall them a trial or there befall them a torment afflictive. 63 Now surely Allah's is whatever is in the heavens and the earth; He knows indeed that to which you are conforming yourselves; and on the day on which they are returned to Him He will inform them of what they did; and Allah is Cognizant of all things. 64
