The Qiraʼat are different linguistic, lexical, phonetic, morphological and syntactical forms permitted with reciting the Quran.
Each of the ten Qira'at has two riwayat (sing: riwayah), which, although different from each other, are both considered acceptable ways to read the Quran.
[8] Abu 'Amr ibn al-'Ala' al-Basri was a Qāriʾ from a branch of the Banu Tamim,[9] He studied under Ibn Abi Ishaq, and was a renowned scholar of Arabic grammar in addition to his knowledge of the Quran, founding the Basran school of grammar.
[14] Although he never met Sibawayhi, the ethnic Persian considered the father of Arabic grammar, Sibawayhi quotes from Abu 'Amr 57 times in his well-known Kitab, mostly by transmission from Ibn Habib and al-Farahidi.
[15] In addition to Al-Soussi, Ibn al-'Ala's Qira'ah was also transmitted by Al-Duri.
