Abu Sa‘īd al-Khudri (may Allah be pleased with him) reported: The Messenger of Allah (may Allah's peace and blessings be upon him) said: "When anyone of you is in doubt about his prayer, not knowing how much he prayed, three or four, let him dispel the doubt and build upon what he is certain about, then perform two prostrations before making Taslīm. If he has prayed five, they will make his prayer even-numbered, and if he has prayed exactly four, they will be humiliation for the devil."
Where the Encyclopedia of Translated Prophetic Hadiths (HadeethEnc.com) has the very text of a narration, its translation stands under that narration and is named. The two were paired by program, from the Arabic alone: the entry’s whole text, with the Companion it names, is the end of the narration letter for letter. Nobody has checked the pairing, and Sabīl’s reviewers have not examined the translation. The Arabic is the text.
The Arabic text, the numbering, the book names and the gradings are shown exactly as they stand in an open dataset (hadith-api). Sabīl has not yet verified its accuracy or its rights, and its scholarly review has not begun. Until then, check a narration against a printed edition before relying on it.
