Hadith 4:934
Abu Khalid al-Ahmar narrated to us, from Ash'ath, from al-Mughirah, from Ibrahim, from Abdullah al-Yashkuri, who said: Abdullah said: "Whoever breaks his fast on a day of Ramadan intentionally, without being on a journey or ill, he shall never be able to make it up, even if he were to fast for his entire life."
حدثنا أبو خالد الأحمر عن أشعث عن مغيرة عن إبراهيم عن عبد الله اليشكري قال قال عبد الله من أفطر يوما من رمضان متعمدا من غير سفر ولا مرض لم يقضه ابدا وان صام الدهر كله
