Al-Albani

Muhammad Nasir ad-Din was born in Shkodër, Albania, and came to Damascus as a child. He worked as a watch repairer and spent long hours in the Zahiriyya library studying manuscripts. He devoted his life to grading hadith, and his verdicts on the Sunan — given for many hadith in this app — are among the most cited today. He taught for a time at the Islamic University of Madinah and received the King Faisal Prize in 1999. He died in Amman.
