Mus'ub bin Sa'd ibn Abi Waqqas مصعب بن سعد بن أبى وقاص الزهرى · Chapters on Supplication

“Fatimah complained to me about her hands blistering from grinding flour. So I said: ‘If you were to approach your father and ask him for a servant?’ So he (the Prophet) said: ‘Should I not direct the two of you, to that which is better for you than a servant? When the two of you lay down to sleep, say thirty-three, thirty-three, thirty-four, of At-Taḥmīd, At-Tasbīḥ, and At-Takbīr.”
