The Prophet ﷺ was given some clothes including a black Khamisa. The Prophet ﷺ said, "To whom shall we give this to wear?" The people kept silent whereupon the Prophet ﷺ said, "Fetch Um Khalid for me." I (Um Khalid) was brought carried (as I was small girl at that time). The Prophet ﷺ took the Khamisa in his hands and made me wear it and said, "May you live so long that your dress will wear out and you will mend it many times." On the Khamisa there were some green or pale designs (The Prophet ﷺ saw these designs) and said, "O Um Khalid! This is Sanah." (Sanah in a Ethiopian word meaning beautiful).  

عَنْ أُمِّ خَالِدٍ بِنْتِ خَالِدٍ أُتِيَ النَّبِيُّ ﷺ بِثِيَابٍ فِيهَا خَمِيصَةٌ سَوْدَاءُ صَغِيرَةٌ فَقَالَ مَنْ تَرَوْنَ نَكْسُو هَذِهِ فَسَكَتَ الْقَوْمُ قَالَ ائْتُونِي بِأُمِّ خَالِدٍ فَأُتِيَ بِهَا تُحْمَلُ فَأَخَذَ الْخَمِيصَةَ بِيَدِهِ فَأَلْبَسَهَا وَقَالَ أَبْلِي وَأَخْلِقِي وَكَانَ فِيهَا عَلَمٌ أَخْضَرُ أَوْ أَصْفَرُ فَقَالَ يَا أُمَّ خَالِدٍ هَذَا سَنَاهْ وَسَنَاهْ بِالْحَبَشِيَّةِ حَسَنٌ  

When Um Sulaim gave birth to a child. she said to me, "O Anas! Watch this boy carefully and do not give him anything to eat or drink until you have taken him to the Prophet ﷺ tomorrow morning for the Tahnik." So the next morning I took the child to the Prophet ﷺ who was sitting in a garden and was wearing a Huraithiya Khamisa and was branding the she-camel on which he had come during the Conquest of Mecca.  

لِي يَا أَنَسُ انْظُرْ هَذَا الْغُلاَمَ فَلاَ يُصِيبَنَّ شَيْئًا حَتَّى تَغْدُوَ بِهِ إِلَى النَّبِيِّ ﷺ يُحَنِّكُهُ فَغَدَوْتُ بِهِ فَإِذَا هُوَ فِي حَائِطٍ وَعَلَيْهِ خَمِيصَةٌ حُرَيْثِيَّةٌ وَهْوَ يَسِمُ الظَّهْرَ الَّذِي قَدِمَ عَلَيْهِ فِي الْفَتْحِ
