وَعَنْ أُمِّ سَلَمَةَ رَضِيَ اللَّهُ عَنْهَا أَنَّهَا كَانَتْ عِنْدَ رَسُولِ اللَّهِ ﷺ وَمَيْمُونَةَ، إِذْ أَقْبَلَ ابْنُ أُمِّ مَكْتُومٍ رَضِيَ اللَّهُ عَنْهُ فَدَخَلَ عَلَيْهِ، فَقَالَ رَسُولُ اللَّهِ ﷺ: «احْتَجِبَا مِنْهُ»، فَقُلْتُ: يَا رَسُولَ اللَّهِ! أَلَيْسَ هُوَ أَعْمَى؟ لَا يُبْصِرُنَا، فَقَالَ رَسُولُ اللَّهِ ﷺ: «أَفَعَمْيَاوَانِ أَنْتُمَا؟ أَلَسْتُمَا تُبْصِرَانِهِ؟» (Ahmad, Tirmidhi and Abu Dawud, as printed)
Translation: Umm Salamah reported that she and Maymunah were with the Prophet ﷺ when Ibn Umm Maktum entered. The Prophet ﷺ directed the two women to cover. Umm Salamah asked why, since he was blind and could not see them. The Prophet ﷺ replied, “Are you two also blind? Do you not see him?”
The exchange points not only to the visitor's sight but also to the responsibility of those present for their own looking and conduct.
