حَدَّثَنِي مَالِكٌ، عَنْ صَفْوَانَ بْنَ سُلَيْمٍ، عَنْ عَطَاءِ بْنِ يَسَارٍ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم سَأَلَهُ رَجُلٌ فَقَالَ يَا رَسُولَ اللَّهِ أَسْتَأْذِنُ عَلَى أُمِّي فَقَالَ ‏"‏ نَعَمْ ‏"‏ ‏.‏ قَالَ الرَّجُلُ إِنِّي مَعَهَا فِي الْبَيْتِ ‏.‏ فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ اسْتَأْذِنْ عَلَيْهَا ‏"‏ ‏.‏ فَقَالَ الرَّجُلُ إِنِّي خَادِمُهَا ‏.‏ فَقَالَ لَهُ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ اسْتَأْذِنْ عَلَيْهَا أَتُحِبُّ أَنْ تَرَاهَا عُرْيَانَةً ‏"‏ ‏.‏ قَالَ لاَ ‏.‏ قَالَ ‏"‏ فَاسْتَأْذِنْ عَلَيْهَا ‏"‏ ‏.‏

The Messenger of Allah. may Allah bless him and granthim peace, said, "Ask her permission. Do you want to see her naked?"He said, "No." He said, "Then ask her permission." Translation Not Available
