Hospitality and guest-rights

قَالَ إِنَّ هَـٰٓؤُلَآءِ ضَيْفِى فَلَا تَفْضَحُونِ

[Lot] said, "Indeed, these are my guests, so do not shame me.

إِذْ دَخَلُوا۟ عَلَيْهِ فَقَالُوا۟ سَلَـٰمًا ۖ قَالَ سَلَـٰمٌ قَوْمٌ مُّنكَرُونَ

When they entered upon him and said, "[We greet you with] peace." He answered, "[And upon you] peace; [you are] a people unknown."
