Abū Bakr 'Abdollāh b. Moḥammad b. Šahāvar b. Anūšervān al-Rāzī (Persian: نجمالدین رازی) commonly known by the laqab, or sobriquet, of Najm al-Dīn Dāya, meaning "wetnurse" (573 AH/1177 – 654 AH/1256) was a 13th-century Sufi.
Dāya traveled to Kārazm and soon became a morīd (pupil, one who follows the shaykh master and learns from him, undergoing spiritual training[2]) of Najm al-Dīn Kubrā.
[citation needed] There he put the teachings of his master Najm ad-Din Kubra into a writing in Persian called by the Arabic title Mirṣād al-ʻibād min al-mabdaʼ ilāʼl-maʻād (ِِArabic: مرصاد العباد من المبدأ الی المعاد) which is shortly known as Merṣād al-ʻebād, and has gained prominence as a major reference text on Sufism and Islamic theology.
[citation needed] He finally settled in Khwārazm and soon become a murīd to Najm al-Dīn Kubrā, a mystical Sufi and founder of the Kubrawiya Order.
[citation needed] At Malatya, Razi met Shaikh Sehab al-Din Abu Hafs ‘Omar al-Sohravardi, nephew of the founder of the Sohravardi order.
It deals, in a systematic manner, with the origins of the various realms and orders of creation, prophethood and the different dimensions of religion, the ritual practices, mores, and institutions of Sufism, the destinations that await different classes of men in the hereafter, and the fashion in which different professions and trades may come to yield spiritual benefit and heavenly reward.
[10] Another prominent feature of the book is the frequency with which it draws parallels between the inner and the outer worlds, particularly with references to processes of growth and development i.e. seed, tree, branch, fruit; the emergence of the hen from the egg.
