﴿ يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوا۟ لِيَسْتَـْٔذِنكُمُ ٱلَّذِينَ مَلَكَتْ أَيْمَٰنُكُمْ وَٱلَّذِينَ لَمْ يَبْلُغُوا۟ ٱلْحُلُمَ مِنكُمْ ثَلَٰثَ مَرَّٰتٍۢ ۚ مِّن قَبْلِ صَلَوٰةِ ٱلْفَجْرِ وَحِينَ تَضَعُونَ ثِيَابَكُم مِّنَ ٱلظَّهِيرَةِ وَمِنۢ بَعْدِ صَلَوٰةِ ٱلْعِشَآءِ ۚ ثَلَٰثُ عَوْرَٰتٍۢ لَّكُمْ ۚ لَيْسَ عَلَيْكُمْ وَلَا عَلَيْهِمْ جُنَاحٌۢ بَعْدَهُنَّ ۚ طَوَّٰفُونَ عَلَيْكُم بَعْضُكُمْ عَلَىٰ بَعْضٍۢ ۚ كَذَٰلِكَ يُبَيِّنُ ٱللَّهُ لَكُمُ ٱلْءَايَٰتِ ۗ وَٱللَّهُ عَلِيمٌ حَكِيمٌۭ ﴾

“O YOU who have attained to faith! At three times [of day], let [even] those whom you rightfully pos­sess, as well as those from among you who have not yet attained to puberty, ask leave of you [before intruding upon your privacy]: before the prayer of daybreak, and whenever you lay aside your garments in the middle of the day, and after the prayer of nightfall: the three occasions on which your nakedness is likely to be bared. Beyond these [occasions], neither you nor they will incur any sin if they move [freely] about you, attending to [the needs of] one another. In this way God makes clear unto you His mes­sages: for God is all-knowing, wise!”

(O ye who believe! Let your slaves, and those of you who have not come to puberty, ask leave of you�) [24:58]. Said ibn �Abbas: �The Messenger of Allah, Allah bless him and give him peace, sent a boy from the Helpers, called Mudlij ibn �Amr, to �Umar ibn al-Khattab, May Allah be pleased with him, after noon to summon him. When he entered in, he saw �Umar in a state which the latter disliked to be seen in. And so he said to the Prophet: �O Messenger of Allah, I wish that Allah, exalted is He, give us some commands and prohibitions regarding asking permission before entering�. And so Allah, exalted is He, revealed this verse�. Said Muqatil: �This verse was revealed about Asma� bint Marthid. She had a slave-boy who was quite old and he happened to enter in on her one day at a time in which she disliked him to enter in on her. She went to the Messenger of Allah, Allah bless him and give him peace, and said: �Our servants and slaves enter in on us and find us in states in which we dislike them to see us�. Allah, exalted is He, then revealed this verse�.
