It is narrated from Sayyidah Umm Khalid bint Khalid (may Allah be pleased with her) that some garments were brought to the Messenger of Allah (peace and blessings be upon him), among which was a black sheet (khamisah). He (peace and blessings be upon him) asked his Companions: "Who do you think is most deserving of this sheet?" They all remained silent. Then he (peace and blessings be upon him) called Umm Khalid and himself dressed her in that sheet, then said: "O my little daughter, wear it until it becomes old and worn out (that is, may you live long)." He (peace and blessings be upon him) repeated this three times. That sheet had red markings on it, and he (peace and blessings be upon him) began to say: "O Umm Khalid, sana!" In the Abyssinian language, 'sana' means beautiful. This hadith is sahih (authentic) on the condition of the two Shaykhs (Bukhari and Muslim), but they did not record it.
