Question: I am seeking knowledge and Eemaan (Faith) that may please Allaah and His Messenger (peace and blessings of Allaah be upon him).
Which Islaamic books would you advise me to read to strengthen me, especially nowadays when there are many books that contain doubtful matters and falsehoods about the Deen (religion)?
Secondly: What is the ruling, in your understanding, on the Sufi Tariqahs (orders) in general, and the Naqshabandiyyah order in particular?
Answer: Firstly, you should devote your attention to the Qur’aan, reciting it regularly and contemplating its meanings, as the Qur’aan is the root of all that is good. You should then attend to the Sunnah of the Prophet (peace and blessings of Allaah be upon him). We recommend the following books on Tawheed (Islaamic monotheism):
“Sharh Al-`Aqeedah Al-Tahaawiyyah”, “Tat-heer Al-I`tiqaad” by Al-San`aanee, “Al-Tawheed” by Ibn Khuzaymah, “Mukhtasar Al-Sawaa`iq Al-Mursalah” by Al-Mawsilee. “Kashf Al-Shubuhaat” and “Al-Tawheed” by Shaykh Muhammad ibn `Abdul-Wahhaab, “Al-`Aqeedah Al-Wasitiyyah” by Ibn Taymiyyah, along with its commentaries, and also his two books: “Al-Hamawiyyah” and “Al-Tadmooriyyah.”… read more here.
