Imam Mohammad Hayyat ibn Ibraaheem al-Sindi (Arabic) امام الشيخ محمد حياة بن ابراهيم السندي )(d. ca. 1750 ): was a prominent Muslim scholar, chancelor of Al-Masjid al-Nabawi and Chief Justice of Medina in the eighteen-century during the period of Ottoman Empire.
Ibn Abd-al-Wahhab's teacher Abdallah ibn Ibrahim ibn Sayf introduced the relatively young man to Mohammad Hayya Al-Sindhi in Medina and recommended him as a student. Ibn Abd-al-Wahhab and al-Sindi became very close and Ibn Abd-al-Wahhab stayed with him for some time. Al-Sindi was a renowned scholar of hadith who was well known for repudiating innovations. Scholars have described Muhammad Hayya as having an important influence on Ibn Abd-al-Wahhab, encouraging him to denounce rigid imitation of medieval commentaries and to utilize informed individual analysis (ijtihad). Muhammad Hayya also taught Ibn Abd-al-Wahhab to reject popular religious practices associated with 'saints' and their tombs that resembles later Wahhabi teachings. Muhammad Hayya and his milieu are important for understanding the origins of at least the Wahhabi revivalist impulse.[1]
He passed away on Wednesday, the 26th of Safar, 1163H in Medina, and was buried in the Jannat al Baqi .[2]
