The reports about him [spread], people traveled to him, and they heard from him. He died in the year five hundred and twelve, and his birth was in the year four hundred and thirty-five(1).

8 - ʿUmar ibn al-Ḥasan ibn ʿAbd al-Raḥmān ibn ʿUmar, Abū Ḥafṣ al-Hawzanī al-Ishbīlī. He traveled to the East in the year four hundred and forty-four, and performed the pilgrimage. Ibn Khazraj said: He was versatile in the sciences, having taken from every branch thereof a plentiful share, along with the acuteness of his understanding and the soundness of his precision. His birth was in the year three hundred and ninety-two, and al-Muʿtaḍid bi-llāh ʿAbbād killed him unjustly in his palace, and that was in the year four hundred and sixty(2).

Now that we have come to the description of these sources photographed from the manuscript copies found in the world's libraries—and although they are sufficient in themselves—we have added to them the references that have also undertaken the care of the book al-Jāmiʿ in producing this edition, such as the book "Tuḥfat al-Ashrāf bi-Maʿrifat al-Aṭrāf" by the imam, the precise ḥāfiẓ, Jamāl al-Dīn Abū al-Ḥajjāj Yūsuf al-Mizzī, who died in the year (742) AH. This book of his is an indexed dictionary of the musnads of the Companions and those who narrated from them, and a scholarly encyclopedia of all the ḥadīths of the six books. He, may God have mercy on him, relied on sound and precise sources of these six books.

Among the sources from which we benefited and to which we referred is "al-Nafḥ al-Shadhī fī Sharḥ al-Tirmidhī," authored by Abū al-Fatḥ Muḥammad ibn Muḥammad ibn Muḥammad ibn Sayyid--------------------------------------------
