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 ʿAisha of her need. When he came, ʿAisha informed him about it. ʿAli added: The Prophet ﷺ 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 ﷺ 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-three 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." (Using translation from Bukhārī 6318)
