A fasting person forgetfully eating and drinking

Q 5: If one eats or drinks forgetfully during a day in Ramadan, should one make up for the Sawm (Fast) of that day? The Messenger (peace be upon him) said: "Anyone who forgets that they are fasting and eats or drinks..."? He (peace be upon him) also said: My Ummah (nation based on one creed) has been pardoned for what they do by mistake, forgetfully, or under duress.

A: Anyone who eats or drinks forgetfully during the daytime in Ramadan is not sinful and should complete their Sawm and not break it. Moreover, they need not make up for the Sawm of the day in question, according to the more correct of the two opinions maintained by scholars. This is the view maintained by Al-Shafi`y and Imam Ahmad based on the Hadith related by Al-Bukhari and Muslim to the effect that the Prophet (peace be upon him) said: Anyone who forgets that they are fasting and eats or drinks should complete their Sawm, for it is Allah Who fed them and gave them something to drink. According to another wording: If a fasting person eats or drinks something forgetfully, it is something with which Allah provided him and he does not have to make up for the fast of that day.
