Hadith 781
. . . أفعمياوان أنتما ؟ ألستما تبصرانه
"Umm Salamah and Maymunah (may Allah be pleased with them) were with the Prophet (peace be upon him) when suddenly Ibn Umm Maktum (may Allah be pleased with him) came to him. Upon this, the Prophet (peace be upon him) said: 'Both of you observe veiling from him.' Umm Salamah (may Allah be pleased with her) said: 'O Messenger of Allah! This person is blind; he cannot see us.' So the Prophet (peace be upon him) said: 'Are you both blind as well? Do you not see him?'"
