Hadith 4:266
Ibn ‘Ulayyah narrated to us, from Ma’mar, from al-Zuhri, from ‘Ubayd Allah ibn ‘Abd Allah, from Ibn ‘Abbas regarding the making up of Ramadan: "Fast it however you wish." And Ibn ‘Umar said: "Fast it just as you broke it."
حدثنا بن علية عن معمر عن الزهري عن عبيد الله بن عبد الله عن بن عباس في قضاء رمضان صمه كيف شئت وقال بن عمر صمه كما أفطرته
