Sahih al-Bukhari 6281
Narrated Thumama:
Anas said, "Um Sulaim used to spread a leather sheet for the Prophet (ﷺ) and he used to take a midday 
nap on that leather sheet at her home." Anas added, "When the Prophet (ﷺ) had slept, she would take 
some of his sweat and hair and collect it (the sweat) in a bottle and then mix it with Suk (a kind of 
perfume) while he was still sleeping. "When the death of Anas bin Malik approached, he advised that 
some of that Suk be mixed with his Hanut (perfume for embalming the dead body), and it was mixed 
with his Hanut.
حَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، حَدَّثَنَا مُحَمَّدُ بْنُ عَبْدِ اللَّهِ الأَنْصَارِيُّ، قَالَ حَدَّثَنِي أَبِي، عَنْ ثُمَامَةَ، عَنْ أَنَسٍ، أَنَّ أُمَّ سُلَيْمٍ، كَانَتْ تَبْسُطُ لِلنَّبِيِّ صلى الله عليه وسلم نِطَعًا فَيَقِيلُ عِنْدَهَا عَلَى ذَلِكَ النِّطَعِ ـ قَالَ ـ فَإِذَا نَامَ النَّبِيُّ صلى الله عليه وسلم أَخَذَتْ مِنْ عَرَقِهِ وَشَعَرِهِ، فَجَمَعَتْهُ فِي قَارُورَةٍ، ثُمَّ جَمَعَتْهُ فِي سُكٍّ ـ قَالَ ـ فَلَمَّا حَضَرَ أَنَسَ بْنَ مَالِكٍ الْوَفَاةُ أَوْصَى أَنْ يُجْعَلَ فِي حَنُوطِهِ مِنْ ذَلِكَ السُّكِّ ـ قَالَ ـ فَجُعِلَ فِي حَنُوطِهِ‏.‏
