Etiquette when entering the house of the Prophet (peace and blessings be upon him) and the order for covering

O you who believe, do not enter the houses of the Prophet for a meal without awaiting the proper time, unless asked, and enter when you are invited, and depart when you have eaten, and do not stay on talking. This puts the Prophet to inconvenience, and he feels embarrassed before you; but God is not embarrassed in (saying) the truth. And when you ask his wife for some thing of utility, ask for it from behind the screen. This is for the purity of your hearts and theirs. It does not behove you to annoy the prophet of God, or to ever marry his wives after him. This would indeed be serious in the sight of God.

Whether you discuss a thing or conceal it, surely God has knowledge of everything.

There is no harm if they come before their fathers or their sons, or their brothers and their brothers' and sisters' sons, or their women folk or captive maids they possess. Follow the commands of God. Verily God is witness to everything.
