وحَدَّثَنِي مُحَمَّدُ بْنُ رَافِعٍ ، حَدَّثَنَا حُجَيْنُ بْنُ الْمُثَنَّى ، حَدَّثَنَا عَبْدُ الْعَزِيزِ ، وَهُوَ ابْنُ أَبِي سَلَمَةَ ، عَنْ إِسْحَاقَ بْنِ عَبْدِ اللهِ بْنِ أَبِي طَلْحَةَ ، عَنْ أَنَسِ بْنِ مَالِكٍ ، قَالَ : كَانَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَدْخُلُ بَيْتَ أُمِّ سُلَيْمٍ فَيَنَامُ عَلَى فِرَاشِهَا ، وَلَيْسَتْ فِيهِ ، قَالَ : فَجَاءَ ذَاتَ يَوْمٍ فَنَامَ عَلَى فِرَاشِهَا ، فَأُتِيَتْ فَقِيلَ لَهَا : هَذَا النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ نَامَ فِي بَيْتِكِ ، عَلَى فِرَاشِكِ ، قَالَ فَجَاءَتْ وَقَدْ عَرِقَ ، وَاسْتَنْقَعَ عَرَقُهُ عَلَى قِطْعَةِ أَدِيمٍ ، عَلَى الْفِرَاشِ ، فَفَتَحَتْ عَتِيدَتَهَا فَجَعَلَتْ تُنَشِّفُ ذَلِكَ الْعَرَقَ فَتَعْصِرُهُ فِي قَوَارِيرِهَا ، فَفَزِعَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَقَالَ : مَا تَصْنَعِينَ ؟ يَا أُمَّ سُلَيْمٍ فَقَالَتْ : يَا رَسُولَ اللهِ ، نَرْجُو بَرَكَتَهُ لِصِبْيَانِنَا ، قَالَ : أَصَبْتِ.

It was narrated that Anas bin Malik said: “The Prophet (s.a.w) used to enter the house of Umm Sulaim and sleep on her bed when she was not there. He came one day and slept on her bed, then she came and it was said to her: ‘The Prophet (s.a.w) is sleeping in your house, on your bed.’ She came, and he had begun to sweat, and the sweat had fallen onto the leather cloth that was on the bed. She opened her jewelry box and started to wipe up that sweat and squeeze it into her bottles. The Prophet (s.a.w) woke up and said: ‘What are you doing, O Umm Sulaim?’ She said: ‘O Messenger of Allah, we hope for blessing for our children.’ He said: ‘You have done right.”’
