Hadith 4:187
Abu Dawud narrated to us, from Hammad ibn Salamah, from Sa'id ibn Qatan, from his father, who said: He was with Mu'awiyah during Ramadan, and they broke their fast. Then the sun appeared, so he ordered them to make up the day.
حدثنا أبو داود عن حماد بن سلمة عن سعيد بن قطن عن أبيه قال كان عند معاوية في رمضان فافطروا ثم طلعت الشمس فامرهم ان يقضوا
