Imam Muslim apart from attending the lessons of Imam Bukhari regularly, also attended the lectures of Imam Ahmad bin Hambal, Abdullah al Qarri, Qutaiba bin Said, Abdullah bin Maslama and other great Muhadith.
Sheikh Abdul Latief says Imam Tirmidhi and Imam Muslim were followers of the Shafee school of thought, although they were both Mujtahids. Moulana Abdur-Rashid says that Imam Muslim was a Maliki. The fact is what was said by Sheikh Tahir Jazari that Imam Muslim is not a Maliki nor a Hanifi nor a Shafi, but his compilation of the Sahih Muslim shows that he was more inclined towards the Shafee school of thought.
His most noted students are Hatim Razi, Ahrnad bin Salmah, Abu Isa Tinnizi, Abubaker bin Khuzaima and other great scholars.
