As-Sunan al-Kubra li al-Bayhaqi, also known as al-Sunan al-Kabir, is a collection of hadith and athar compiled by Imam Abu Bakr Ahmad ibn al-Husayn ibn `Ali al-Bayhaqi (d. 458 AH/1066 CE - rahimahullah). It is a major topical collection arranged by legal chapters, gathering reports from the Prophet Muhammad (ﷺ) together with reports from the Companions and early authorities, often with variant routes and hadith-critical discussion. Its stature is reflected in al-Dhahabī’s praise: he counted al-Bayhaqī’s al-Sunan al-Kabīr alongside Ibn Ḥazm’s al-Muḥallā, Ibn Qudāmah’s al-Mughnī, and Ibn ʿAbd al-Barr’s al-Tamhīd as works whose deep study makes one “the true scholar.” It contains approximately 22,000 reports.
