Or 1040

The well-known religious poem of Yazıcıoğlu Mehmet Efendi. Mehmet bin Salih, also known in Arabic as Ibn al-Kātib, or as Yazıcıoğlu in Turkish, is often connected to his brother Ahmet Bijan. He was a native of Malgara near Edirne, as mentioned in the commentary of İsmail Hakkı, and became a disciple and halife of the mystic Şeyh Haci Bayram in Ankara. He spent most of his life in religious seclusion at Galipoli, where he died in 855 AH (1451-52 CE). In addition to the current work, he is also known for a commentary on the Fusus ul-Hikem.

This poem is also known as the Muhammadiye. It is an exposition of traditions and doctrines within Islam based on texts from the Qur'an and the Hawādith. It deals especially with the divine mission of the Prophet Muhammad صلعم, with his life, with the end of the world, paradise, hell, and similar subjects.

The epilogue of the poem contains an account of the visions in which the Prophet Muhammad صلعم and Haci Bayram appeared to the author; eulogies on the two Sultans then living, Murat II and Mehmet II; and on the author's patron, Vezir Mahmud Paşa İbn-i Kasap. After describing his former work, the Maghārib, and his brother Bijan's Ottoman Turkish version, Envar ul-Aşikin, the author says that the latter work and the present were both the product of a surfeit of material from the Maghārib.

The original poem was completed in Cemaziulahir 853 AH (July-August 1449 CE), as stated on f 308v.

The current manuscript was copied by Yahya İbn-i Abdallah and completed in Safer 1049 AH (June 1639 CE).
