Abu Bakr ‘Aasim Ibn Abi al-Najud al-'Asadi (died 745 CE / 127 AH),[1][2] commonly known as ‘Aasim ibn Abi al-Najud, was, according to Islamic tradition, one of the seven primary transmitters of the Qira'at, or variant readings of the Qur'an.
[4] Though he lived much of his life in Kufa, he was associated with Banu Asad ibn Khuzaymah due to a pact.
[5] Unlike most reciters in Kufa, he did not accept the pre-Uthmanic style of the Qur'an written by the companion of the Prophet, Abdullah ibn Masud;[5] most of the people of Kufa continued reciting based on that style for a period even after the Uthmanic version became canon.
[1] Eventually this changed with the standardisation of the mushaf, and in time Aasim's reading became the norm for the Muslim world.
[2] The Warsh 'an Naafi' recitation of the Quran differs from Hafs 'an Aasim' in orthography.
