An-Nur 24:61 ليس على الاعمى حرج ولا على الاعرج حرج ولا على المريض حرج ولا على انفسكم ان تاكلوا من بيوتكم او بيوت ابايكم او بيوت امهاتكم او بيوت اخوانكم او بيوت اخواتكم او بيوت اعمامكم او بيوت عماتكم او بيوت اخوالكم او بيوت خالاتكم او ما ملكتم مفاتحه او صديقكم ليس عليكم جناح ان تاكلوا جميعا او اشتاتا فاذا دخلتم بيوتا فسلموا على انفسكم تحية من عند الله مباركة طيبة كذالك يبين الله لكم الايات لعلكم تعقلون ٦١

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 Allâh (i.e. say: السلام عليكم) As-Salâmu ‘Alaikum - peace be on you) blessed and good. Thus Allâh makes clear the Ayât (these Verses or your religious symbols and signs) to you that you may understand.
