Every Qur'anic verse on this site is taken from the canonical Madinah mushaf (via the Tanzil text database). Every hadith is taken from the primary editions on sunnah.com, with the narrator, the grading authority (al-Bukhari, Muslim, al-Albani, Darussalam etc.), and the grade itself recorded alongside it. Before any verse or hadith can appear on a page, the Arabic text is registered in our reference register. An automatic check then runs before every release: if so much as a single letter of an Arabic matn has been altered, the release stops until a researcher has reviewed the change. In practice, this means a careless edit cannot replace an authentic narration with an inauthentic one.
Disputed material is flagged. Where scholars differ, the page carries a scholar-review badge and presents one mainstream position with a note that another exists. Da'if hadith are explicitly labelled Da'if; we never present a weak narration as if it were Sahih. Where a famous practice (for example the specific enumeration of the 99 Names) has weaker support than commonly assumed, the page says so openly.
