Hadrat Sayyid Sherîf Jurjânî, one of the great savants of the Hanafî Madhhab, writes at the end of Sharh-i mawâqif and at the beginning of Hâshiyatu Sharh-ul-matâlî’ and in Berîqa, p.270, the figures of the Awliyâ show themselves to their murîds even after their death and give them fayd. To see them and receive fayd is not easy; it is necessary to hold the belief of Ahl as-sunnat by learning it from books, to obey the Ahkâm-i-islâmiyya, and to like and to respect the Awliyâ.  It is written in the book Maraj-ul-bahrayn: “All great men of Tasawwuf were Sunnî Muslims, None of the holders of bid’at attained the Ma’rifat of Allâhu ta’âlâ. The nûr of Wilâyat did not enter their hearts. The darkness of bid’ats, in practices pertaining to worship as well as in tenets of belief, prevented the nûr of Wilâyat from entering their hearts. Unless the dirt of bid’at is removed from the heart, and if the heart is not ornamented with the Ahl-i sunnat belief, the rays of the sun of haqîqat will not enter the heart. Such a heart will not be illuminated by the nûr of yaqîn.” Endless Bliss First Fasicle | Page 285
