Sahih al-Bukhari, Book 80, Hadith 15 (In-Book) ⓘ

Narrated `Ali: Fatima complained about the blisters on her hand because of using a mill-stone. She went to ask the Prophet for servant, but she did not find him (at home) and had to inform `Aisha of her need. When he came, `Aisha informed him about it. `Ali added: The Prophet came to us when we had gone to our beds. When I was going to get up, he said, "'Stay in your places," and sat between us, till I felt the coolness of the feet on my chest. The Prophet then said, "Shall I not tell you of a thing which is better for you than a servant? When you (both) go to your beds, say 'Allahu Akbar' thirty-four times, and 'Subhan Allah' thirty-three times, 'Al hamdu 'illah' thirty-three times, for that is better for you than a servant." Ibn Seereen said, "Subhan Allah' (is to be said for) thirty-four times."

حَدَّثَنَا سُلَيْمَانُ بْنُ حَرْبٍ، حَدَّثَنَا شُعْبَةُ، عَنِ الْحَكَمِ، عَنِ ابْنِ أَبِي لَيْلَى، عَنْ عَلِيٍّ، أَنَّ فَاطِمَةَ ـ عَلَيْهِمَا السَّلاَمُ ـ شَكَتْ مَا تَلْقَى فِي يَدِهَا مِنَ الرَّحَى، فَأَتَتِ النَّبِيَّ صلى الله عليه وسلم تَسْأَلُهُ خَادِمًا، فَلَمْ تَجِدْهُ، فَذَكَرَتْ ذَلِكَ لِعَائِشَةَ، فَلَمَّا جَاءَ أَخْبَرَتْهُ‏.‏ قَالَ فَجَاءَنَا وَقَدْ أَخَذْنَا مَضَاجِعَنَا، فَذَهَبْتُ أَقُومُ فَقَالَ ‏"‏ مَكَانَكِ ‏"‏‏.‏ فَجَلَسَ بَيْنَنَا حَتَّى وَجَدْتُ بَرْدَ قَدَمَيْهِ عَلَى صَدْرِي فَقَالَ ‏"‏ أَلاَ أَدُلُّكُمَا عَلَى مَا هُوَ خَيْرٌ لَكُمَا مِنْ خَادِمٍ، إِذَا أَوَيْتُمَا إِلَى فِرَاشِكُمَا، أَوْ أَخَذْتُمَا مَضَاجِعَكُمَا، فَكَبِّرَا ثَلاَثًا وَثَلاَثِينَ، وَسَبِّحَا ثَلاَثًا وَثَلاَثِينَ، وَاحْمَدَا ثَلاَثًا وَثَلاَثِينَ، فَهَذَا خَيْرٌ لَكُمَا مِنْ خَادِمٍ ‏"‏‏.‏ وَعَنْ شُعْبَةَ عَنْ خَالِدٍ عَنِ ابْنِ سِيرِينَ قَالَ التَّسْبِيحُ أَرْبَعٌ وَثَلاَثُونَ‏.‏
