His name was ‘Isaa bin Meenaa and was nicknamed Aba Musaa. He was of Roman heritage. His Sheikh, Imam Naafi’, nicknamed him Qaloon because of the quality of his qira’ah. The word Qaloon in the Roman language means “good.” He was born in 120 Al-Hijara and died 220 Al-Hijara in Al-Medinah.
He was deaf and could not even hear a horn, but if someone recited the Qur’an to him, he could hear. Some biographies say the deafness came when he was older, but others mention it as if he was always deaf, and Allah knows best. The basic rules of the riwaayah of Qaloon 'an Naafi' and available below, with links to each lesson listed. The special words though, must be obtained from a mushaf that has the recitation of Qaloon or a mushaf of the ten qira'aat.
