O you who believe, let your dependants and those who have not yet reached the age of puberty, ask permission (to enter your presence) on three occasions: Before the early morning prayer; when you disrobe for the mid-day siesta; and after prayer at night. These are the three occasions of dishabille for you. There is no harm if you or they visit one another at other times (without permission). God thus explains things to you clearly, for God is all-knowing and all-wise. 58 When your children have reached the age of puberty, they should similarly ask your leave (for entering) as others did before them. God thus clearly explains His commands to you, for God is all-knowing and all-wise. 59 Elderly women who have no hope of getting married are allowed not to wear the kind of clothing that young woman must wear, as long as they do not show off their beauty. It is better for them if they maintain chastity. God is All-hearing and All-knowing. 60 There is no restriction on the blind, nor any restriction on the lame, nor any restriction on the sick, nor on yourselves, if you eat from your houses, or the houses of your fathers, or the houses of your mothers, or the houses of your brothers, or the houses of your sisters, or the houses of your father's brothers, or the houses of your father's sisters, or the houses of your mother's brothers, or the houses of your mother's sisters, or (from that) whereof you hold keys, or (from the house) of a friend. No sin on you whether you eat together or apart. But when you enter the houses, greet one another with a greeting from Allah (i.e. say: As-Salamu 'Alaikum - peace be on you) blessed and good. Thus Allah makes clear the Ayat (these Verses or your religious symbols and signs, etc.) to you that you may understand. 61
