The opening as it read in 2005

Al-Tirmidhi , full name Abu Isa Muhammad ibn Isa ibn Musa ibn al-Dahhak al-Sulami al-Tirmidhi ( 824 - 892 , ie 209 AH - 13 Rajab 279 AH) was a medieval collector of hadith (sayings of Muhammad ), who wrote the Jami at-Tirmidhi , one of the six canonical hadith compilations used in Sunni Islam . He was born (and would die) at Bugh , a suburb of Termez , to a family of the widespread Banu Sulaym tribe. Starting at the age of twenty, he travelled widely, to Kufa , Basra , and the Hijaz , seeking out knowledge from, among others, Qutaiba ibn Said , Bukhari , Imam Muslim , and Abu Dawud . He was blind in the last two years of his life. He wrote nine books, of which, after the Jami , al-Ilal is best-known; only four of his works survive. He played a major part in giving the formerly vague terminology used in classifying hadith according to their reliability a more precise set of definitions. v t e1
