As for Dawud, the leader of the literalists, he wrote a lot on belief along with his many writings on jurisprudence. His son, Abu Bakr,
Muhammd ibn Dawud ibn Ali ibn Khalaf Al Dhahiri (255 h. – 297 h.) was an Imam and son of the Imam Dawud Al Dhahiri. He took over his fathers position as a Mufti and teacher after his father. (Source: Al A`laam).
was a scholar of jurisprudence, Kalam <belief>, methodology, literature and poetry.
Abu Al`Abbaas Ibn Surayj
In the manuscript it is written “Ibn Shurayh”, but it is likely a typographical error, and should be Ibn Surayj, because he was the head of the Sunnis at that time and wrote very many books, as indicated by Abu Mansur: Ahmad ibn Umar ibn Surayj Al Baghdadi, Abu Al Abbas (249 h. – 306 h.) the head of the Shafi`is of his time who wrote some 400 books and was a Judge in Shiraz (in today’s Iran). He fought deviant sects and had debates with Dawud Al Dhahiri. (Source: Al A`laam).
the best of this group in these sciences, and he has a critique on the book of Al-Jaruf
Al Jaruf was a philosopher of the school of equality of proofs.
against those who claim equality of proofs
The claim of equality of proofs is when someone looks at the evidences presented by two opponents and then declares himself unable to decide who is right. The book of Al Jaruf, which defended the idea of equality of proofs, was written by a philosopher against Al Jubba`i, who was a Mu`tazilite. This belief of equality of proofs is basically agnosticism, in the sense that they neither affirm nor deny, but its followers fall into three groups: First, those who question the existence of the Creator. Second, those who believe in the Creator, but doubt prophethood. Third, those who believe in the Creator and the prophethood of Muhammd, but have doubts about other beliefs. (See Al Fisal fi-l-Milal by Ibn Hazm).
and it is more complete than the critique of Ibn Al-Rawandi
He seems to mean Abu Al Husayn Ibn Al Rawandi (? h.- 298 h.), who was a philosopher accused of numerous heresies. (Source: Al A`laam).
against them. As for his writings on jurisprudence – Allah knows their number.
Another of the Kalam scholars in the time of Al Ma`mun is Abdullah ibn Sa`eed Al Tamimi,
Abdullah ibn Sa`eed ibn Kullaab, Abu Muhammd Al Qattaan (? – 245), was one of the greatest Kalam scholars of his time. (Source: Al A`laam). He is also mentioned with the last name Al Tamimi by Al Subki in Tabaqaat Al Shafi`iah Al Kubraa. In Tabaqaat Al Shafi`iah it is stated in the biography of Abdullah ibn Sa`eed ibn Kullaab that Abu Hasan Al Ash`ari was heavily influenced by him and by Harith ibn Asad Al Muhasibi
who crushed the Mu`tazilah in the assembly of Al Ma`mun, and scandalized them with his eloquent exposure and clarification of their faults. The remains of his clarifications are in his books. He is the brother of Yahya ibn Sa`eed Al-Qattaan,
Yahya ibn Sa`eed Al Qattaan Al Tamimi, Abu Sa`eed (120 h. – 198) one of the Imams of Hadith science. He gave the Fatwas of Abu Hanifah and is regarded as a highly trustworthy Hafidh. (Source: Al A`laam).
the inheritor of the knowledge of hadith and the master of narrator criticism.
Among the students of Abdullah ibn Sa`eed is Abdul Aziz Al Makki Al Kattaani,
Abdul Aziz ibn Yahya ibn Abdul Aziz Al Kinani Al Makki (? h. – 240) was among the students of Al Shafi`i and debated Bishr Al Marisi. (Source: Al A`laam).
who scandalized the Mu`tazilah in Al Ma`mun’s assembly. Yet another Kalam scholar was, his student, Al Husayn ibn Al Fadl Al Bajali,
Al Husayn ibn Al Fadl ibn Umayr Al Bajali (178 h. – 282 h.) was one of the leaders of the knowledge of the meanings in the Quran. He was originally from Al Kufa, but the governor Abdul Aziz ibn Tahir brought him to Naysabur where he bought a house for him. He stayed there teaching until he died.
the master of Kalam, methodology, Quranic commentary and interpretation. Later scholars relied upon his notes and pointers in interpreting the Quran. He is the one that Abdul Aziz ibn Tahir, the governor of Khurasan <in North East Iran> brought with him to Khurasan, and as a result people said, “He took with him all the knowledge of Iraq to Khurasan.”
Among the students of Abdullah ibn Sa`eed is also Al-Junayd,
Al Junayd ibn Muhammd ibn Al Junayd Al Baghdadi, Abu Al Qaasim, Al Khazzaz (? – 297) was one of the greatest scholars of all time. One of his contemporaries said, “I have not laid my eyes on anyone like Al Junayd. The scribes come to his lessons to learn from his words, the poets for his eloquence, and the Kalam scholars for the meaning of what he says. The great scholars and historian Ibn Al Athir said about Al Junayd: “The top scholar in the world in his time.” He is considered as one of the great imams of Sufism for his compliance to the sciences of Hadith and Quran along with leadership in Sufi knowledge. He said, “Our way is controlled by the Quran and Hadith.” (Source: Al A`laam).
the Shaykh of the Sufis and the Imam of the monotheists. He has an article that is written according to the requirements of the Kalam scholars, but with Sufi expressions.
