Yahya related to me from Malik from Ata ibn Abdullah al-Khurasani that Said ibn al-Musayyab said, "A bedouin came to the Messenger of Allah (ﷺ) beating his breast and tearing out his hair and saying, 'I am destroyed.' The Messenger of Allah (ﷺ) said, 'Why is that?', and he said, 'I had intercourse with my wife while fasting in Ramadan.' The Messenger of Allah (ﷺ) asked him, 'Are you able to free a slave?', and the man said, 'No.' Then he asked him, 'Are you able to give away a camel?', and the man replied, 'No.' He said, 'Sit own,' and someone brought a large basket of dates to the Messenger of Allah (ﷺ) and he said to the man, 'Take this and give it away as sadaqa.' The man said, 'There is no one more needy than me,' and (the Messenger of Allah, may Allah bless him and grant him peace), said, 'Eat them, and fast one day for the day when you had intercourse.' "

Malik said that Ata said that he had asked Said ibn al-Musayyab how many dates there were in that basket, and he said, "Between fifteen and twenty sas.''
