It is stated in Bahjat al-Asraar that Ghawth al-Aa'zam (Radi Allahu Anhu) has said,
"I was given an extremely large register in which the names of my companions and those of my would-be disciples till the Judgement Day were inscribed. I was then told that those people have been blessed due to their spiritual link with me. I asked the angel of Hell whether any of my disciples was in Hell. He replied in the negative.
He (Radi Allahu Anhu) further said,
"I swear by the glory and greatness of my Creator! My hand of protection is above my disciple as the sky is above the earth. Even if my disciple is not righteous, no matter, by the grace of Allah, I am righteous. I swear by the glory and greatness of my Creator! I will not leave the court of my Creator unless I make each and every disciple of mine enter the Paradise."
He (Radi Allahu Anhu) also said,
"Allah has promised me to make my disciples and friends enter Paradise. Therefore, the one who calls himself a disciple of mine, I initiate him into my Spiritual Order and pay attention towards him. I have made the Munkar and Nakeer promise that they would not frighten my disciples in their graves."
