Narrated Nabhan the freed slave of Umm Salamah:

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?'"

حَدَّثَنَا سُوَيْدٌ، حَدَّثَنَا عَبْدُ اللَّهِ، أَخْبَرَنَا يُونُسُ بْنُ يَزِيدَ، عَنِ ابْنِ شِهَابٍ، عَنْ نَبْهَانَ، مَوْلَى أُمِّ سَلَمَةَ أَنَّهُ حَدَّثَهُ أَنَّ أُمَّ سَلَمَةَ حَدَّثَتْهُ أَنَّهَا، كَانَتْ عِنْدَ رَسُولِ اللَّهِ صلى الله عليه وسلم وَمَيْمُونَةُ قَالَتْ فَبَيْنَا نَحْنُ عِنْدَهُ أَقْبَلَ ابْنُ أُمِّ مَكْتُومٍ فَدَخَلَ عَلَيْهِ وَذَلِكَ بَعْدَ مَا أُمِرْنَا بِالْحِجَابِ فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ احْتَجِبَا مِنْهُ ‏"‏ ‏.‏ فَقُلْتُ يَا رَسُولَ اللَّهِ أَلَيْسَ هُوَ أَعْمَى لاَ يُبْصِرُنَا وَلاَ يَعْرِفُنَا فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ أَفَعَمْيَاوَانِ أَنْتُمَا أَلَسْتُمَا تُبْصِرَانِهِ ‏"‏ ‏.‏ قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ ‏.‏
