Depending on reliable books of Dhikr

A: You should rely on the authoritative books of Adhkar that have been compiled by trustworthy scholars, such as: "Al-Adhkar" by Imam Al-Nawawy "Al-Wabil Al-Sayyib min Al-Kalim Al-Tayyib" by Ibn Al-Qayyim, and "Al-Kalim Al-Tayyib" by Shaykh Al-Islam Ibn Taymiyyah. As for the Adhkar that have been written by the Imams of Sufism, most of them contain unlawful invocations or they entail Shirk (associating others with Allah in His Divinity or worship), such as Tawassul (seeking to draw close to Allah through unlawful means) through the creatures and seeking their help besides Allah (Glorified and Exalted be He). Saying that it is not permissible to take invocations from books, but that they should be taken from a righteous person is a falsehood, because Adhkar are taken from the Qur’an and the authentic Books of Hadith.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
