Gürâni was born on August 28, 1406, or in 1410 or in 1411, in a place called Gûrân in Esfarayen or in Shahrizor or near Diyarbekir or near Halabja, and given the name Şemseddin Ahmed b. İsmâil or Şerefeddin or Şehâbeddin.
[1][2] He was later also given the honorific mollâ or mevlânâ and became known by the nisba Gürânî, Şehrizorî, Hemedânî, Tebrîzî, Kâhirî, or Rûmî, thus his usual appellation Molla Gürâni.
[7] After that, he moved on to Cairo, where he studied hadith, qira'at, tafsir, and fiqh, and received his ijazah from Ibn Hajar.
[9][10] Around the time of his punishment, either in Aleppo or Cairo, Gürâni met Ottoman scholar Molla Yegân, who brought him to Sultan Murad II; the sultan appointed him mudarris first in the Kaplıca Madrasa in Bursa and then in the Yıldırım Madrasa.
He was part of Mehmed's council during the conquest of Constantinople and afterward wrote the account of events, the fetihnâme that was sent to the Mamluk sultan.
He was said to have a modest but dignified personality and superior morality, to be uncompromising in knowledge, and to be unhesitant in expressing his opinions.
