Umar bin alHasan bin Ali bin Muhammad bin alJamil bin Farah bin Khalaf bin Qumis bin Mazlal bin Malal bin Badr bin Dihyah bin Farwah, better known as Ibn Dihya alKalbi was a Moorish scholar of both the Arabic language and Islamic studies, and member of the Ahl alBayt. He preferred to be called Abu alKhattab, though at various times he was also referred to as Ibn alJumayyil, Majd alDin, Abu alFadl or simply Ibn Dihya.
While Ibn Diyha is generally acknowledhed to have been born in Valencia, conflicting reports have been given regarding Kalbis exact date of birth. Ibn Khallikan held the view that Kalbi was born in March of 1150, despite the fact that he was personally informed by Kalbis son and nephew that Kalbi was born in February of 1152.
