Abu Huraira said that a man asked the Prophet whether one who was fasting might embrace his wife and he gave him permission, but when another came to him and asked him he forbade him. The one to whom he gave permission was an old man and the one whom he forbade was a youth. Abu Dawud transmitted it.
