Philip Woolley, a professor and researcher from Germany, asked for a copy of al-Sahifa al-Sajjadiyya to be sent to him after his friend, a Roman Catholic Cardinal, saw the book in his library, studied part of it, and impressed with its novelty insisted on taking it away with him. When the Vatican Library in Rome received an English version of al-Sahifa al-Sajjadiyya, it said in its letter of acknowledgment: “This book contains great mystical themes, so we place it for researchers in the best position of the library.” A leader of Germany’s Social Democratic Party wrote to a friend, Professor Singler, saying: “This book had a profound impact on me and changed my view about Islam. I invite my friend to study this book”, while in Poland, Christian Scientist Andre Kowski said of the book: “I am deeply impressed by the ideas of Imam Sajjad, whose noble thoughts are manifested on the pages of the book al-Sahifa al-Sajjadiyya. It is so attractive, to the extent that I feel this book has given me a complete sense of the mystical and divine.
