Someone asked, "Messenger of Allah, what about one who fasts perpetually?"He replied, "He has neither fasted nor broken his fast," or, "He did not fast and did not break his fast."
حدثنا قتيبة وأحمد بن عبدة قالا حدثنا حماد بن زيد عن غيلان بن جرير عن عبد الله بن معبد
قيل يا رسول الله كيف بمن صام الدهر قال لا صام ولا أفطر أو لم يصم ولم يفطر
