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 yourselves like your calling one of another. God knows those of you who slip away surreptitiously; so let those who go against His command beware, lest a trial befall them, or there befall them a painful chastisement. 63 Certainly, to Allah belongs all that is in the heavens and the earth. Surely, He knows your condition and (He knows) the Day when they will be brought back to Him, then He will inform them of what they did. And Allah is All-Knower of everything. 64
