al-Dimashqī, Ibn al-Ḥājib al-Jundī, compiler of The Major Lexicon, one of the brightest of the students and the most diligent among them.
He studied under Hibatu-Allāh ibn Ṭāwūs, Mūsā ibn ʿAbd al-Qādir, al-Muwaffaq, al-Fatḥ, and their contemporaries; he wrote extensively and even authored works before reaching the age of forty.
Those who transmitted from him include Abū Ḥāmid Ibn al-Ṣābūnī and a number of others.

I found in the handwriting of the ḥadīth master al-Ḍiyāʾ: “In Shaʿbān of the year 630 AH our young companion, the ḥadīth scholar Ibn al-Ḥājib, passed away. He was devout, upright, reliable, and keen-minded.”

237 – al-Raḥbī, Raḍī al-Dīn Yūsuf ibn Ḥaydara ibn Ḥasan
The distinguished, eminent scholar and leading physician, Raḍī al-Dīn Yūsuf ibn Ḥaydara ibn Ḥasan al-Raḥbī, the sage.

His father was an oculist from al-Raḥba. Yūsuf was born in al-Jazīra al-ʿUmariyya, then lived for a time in Nisibin and in al-Raḥba. Father and son arrived in Damascus in 555 AH. Yūsuf threw himself into study, manuscript copying, and treating the sick. He kept close company with al-Muhadhdhab Ibn al-Naqqāsh and excelled to the point that al-Muhadhdhab publicised his name. He gained high standing with Sultan Ṣalāḥ al-Dīn, who granted him a stipend of thirty dinars from the Citadel and the hospital; it continued until al-Muʿaẓẓam reduced it, yet he always remained honoured by the state.

He was a leader, lofty in aspiration, deeply exacting, a man of goodness with no trace of harm. He held a teaching chair and trained several prominent physicians.
