’Ubayy ibn Ka‘b (may Allah be pleased with him) reported: The Messenger of Allah (may Allah's peace and blessings be upon him) led us in the Fajr prayer one day and said: "Is so-and-so present?" They replied: 'No.' He said: "Is so-and-so present?" They replied: 'No.' Thereupon, he said: "These two prayers are the most burdensome of all prayers for the hypocrites. If you knew what they contain, you would come to them, even if you had to crawl on your knees. The first row is like that of the angels, and if you knew the nature of its excellence, you would race to join it. A man's prayer with another man is purer than his prayer alone, and his prayer with two men is purer than his prayer with one man; the greater the number, the more pleasing it is to Allah Almighty."
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.
