Mafatih al-Jannah La Ilaha Illa Allah - Muhammad Sultan al-Kanjudi

A wonderful book from a late 19th century scholar who spent his life in the pursuit of science, traveling from present-day Tajikistan, to Bukhara in Uzbekistan, then to Mekkah and Medina, then to the Sham in Damascus and Jerusalem, then to Egypt in Cairo and Alexandria, and finally to Istanbul, before finally returning to his homeland.

He has written some magnificent pages on the meaning and implications of the word Tawhid, La Ilaha Illa Allah. His work was prefaced by Abdallah ibn Hasan Aal ash-Sheikh and Muhammad ibn Ibrahim Aal ash-Sheikh.

A very good, verified and annotated edition.
