(A Hadith similar to no. 716 with a different chain.)

the Prophet said: "Whoever is overcome by vomiting, then he is not required to make up (the fast), and whoever vomits on purpose, then he must make it up."

"Whoever eats or drinks forgetfully, then he has not broken (the fast), for it was only a provision that Allah provided for him."

(Another chain) with the same or similar (Hadith as no. 721).

The Prophet said: "When one of you is invited to eat then let him respond, if he is fasting then let him pray." Meaning: supplicate.
