to Ibn Shihab, that Umm Salamah narrated to him, that she and Maimunah were with the Messenger of Allah ﷺ, she said: "So when we were with him, Ibn Umm Maktum came, and he entered upon him, and that was after veiling had been ordered for us. So the Messenger of Allah ﷺ said: 'Veil yourselves from him.' So I said: 'O Messenger of Allah! Is he not blind such that he can not see us or recognize us?' So the Messenger of Allah ﷺ said: 'Are you two blind such that you can not see him?'" (Using translation from Tirmidhī 2778)   

أَنَّهَا كَانَتْ عِنْدَ رَسُولِ اللهِ ﷺ فَبَيْنَا نَحْنُ عِنْدَهُ أَقْبَلَ ابْنُ أُمِّ مَكْتُومٍ فَدَخَلَ عَلَيْهِ وَذَلِكَ بَعْدَ أَنْ أُمِرَ بِالْحِجَابِ فَقَالَ رَسُولُ اللهِ ﷺ «احْتَجِبَا مِنْهُ» فَقُلْنَا يَا رَسُولَ اللهِ أَلَيْسَ هُوَ أَعْمَى لَا يُبْصِرُنَا وَلَا يَعْرِفُنَا؟ فَقَالَ رَسُولُ اللهِ ﷺ «أَفَعَمْيَاوَانِ أَنْتُمَا؟ أَلَسْتُمَا تُبْصِرَانِهِ؟» قَالَ أَبُو عَبْدِ الرَّحْمَنِ مَا نَعْلَمُ أَحَدًا رَوَى عَنْ نَبْهَانَ غَيْرَ الزُّهْرِيِّ  

[Machine] The Messenger of Allah ﷺ entered upon me and Maimuna while we were sitting. He sat down and then Ibn Umm Maktum, who was blind, came and asked permission to enter. The Prophet ﷺ said, "Cover yourselves from him." We said, "O Messenger of Allah, isn't he blind and cannot see us?" He replied, "Are you both not able to see him?"  

دَخَلَ عَلَيَّ رَسُولُ اللهِ ﷺ وَأنا وَمَيْمُونَةُ جَالِسَتَانِ فَجَلَسَ فَاسْتَأْذَنَ عَلَيْهِ ابْنُ أُمِّ مَكْتُومٍ الْأَعْمَى فَقَالَ «احْتَجِبَا مِنْهُ» قُلْنَا يَا رَسُولَ اللهِ أَلَيْسَ بِأَعْمَى لَا يُبْصِرُنَا قَالَ «فَأَنْتُمَا لَا تُبْصِرَانِهِ؟»
