Ibn Tufail Ibn Tufail (c. 1105 – 1185) (full Arabic name: أبو بكر محمد بن عبد الملك بن محمد بن طفيل القيسي الأندلسي "Abu Bakr Muhammad ibn Abd al-Malik ibn Muhammad ibn Tufail al-Qaisi al-Andalusi"; Latinized form: "Abubacer Aben Tofail"; Anglicized form: "Abubekar" or "Abu Jaafar Ebn Tophail") was a Moorish Andalusian Muslim polymath: a writer, novelist, Islamic philosopher, Islamic theologian, physician, astronomer, vizier, and court official.
Al-Tirmidhi Abū ‘Īsá Muḥammad ibn ‛Īsá as-Sulamī aḍ-Ḍarīr al-Būghī at-Tirmidhī (Arabic: أبو عيسى محمد بن عيسى السلمي الضرير البوغي الترمذي‎ ‎ ; Persian: ‎ ‎ , "Termezī"; 824 – 9 October 892), often referred to as Imām at-Termezī/Tirmidhī, was a Persian Islamic scholar and collector of hadith who wrote "al-Jami` as-Sahih" (known as "Jami` at-Tirmidhi"), one of the six canonical hadith compilations in Sunni Islam. He also wrote "Shama'il Muhammadiyah" (popularly known as "Shama'il at-Tirmidhi"), a compilation of hadiths concerning the person and character of the Islamic prophet, Muhammad. At-Tirmidhi was also well versed in Arabic grammar, favoring the school of Kufa over Basra due to the former's preservation of Arabic poetry as a primary source.
