Narrated Abu Usama from Hisham bin 'Urwa from Fatima: Asma bint Abi Bakr said, We broke our fast during the lifetime of the Prophet on a cloudy day and then the sun appeared. Hisham was asked, Were they ordered to fast in lieu of that day? He replied, It had to be made up for. Ma`mar said, I heard Hisham saying, I don't know whether they fasted in lieu of that day or not.
