(2) And what are the numbers which are used in Tawiz? Is it halal or haram?
بسم الله الرحمن الرحيم
(1) Naqsh-e-Sulaimani is a book of Tawiz. Hakim al-Ummah Hadhrat Maulana Ashraf Ali Thanavi (may Allah have mercy upon him) has forbidden to read it. (Bahishti Zewar, vol. 10, p. 614)
(2) It is lawful to write numbers in the tawiz whose meaning is known as it is an understood. (Ahsanul Fatawa, vol. 8, p. 257, Mutafarriqat al-Hazar al-Ibahat, pub. Zakariah, Deoband)
