Hakim al-Umma Hadhrat Mawlana Shah Ashraf Ali Thanawi (may Allah have mercy on him) said,
“It is in “Fawaidul fawad” (malfuzatof Hazrat Mehboob e Ilahi Khawajah Nizamuddin Awliya Chishti ra) that, salik is he who travels on the path (of sulook). Waqef واقف is the one who is stuck in the middle
If a salik is negligent in his worship but quickly repents, ask (Allah’s) forgiveness and resumes his duties actively he becomes a salik again. However, God-forbid, if he continues to be negligent chance are that he may be turned off راجع
There are seven levels of negligence in this path (sulook).
First is اعراض dodging Allah’s commands
If one does not repent humbly he proceeds to حجاب the creation of a barrier between him & Allah
If he persists this leads to تفاصل increasing separation between him & Allah
If he does not repent even now, the additional state of enthusiasm ذوق و شوق)) in acts of devotion is taken away. This is سلب مزید removal of additional states
If he continues in his foolish ways the comfort and pleasure that were present even before the additional state of enthusiasm are also taken away. This is called سلب قدیم removal of original states
Not repenting and correcting his behavior at this stages leads to an agreement of heart on separation (from Allah). This is called تسلی agreement on separation between him & Allah
If the same negligence continues the love (of Allah) is replaced by عداوت hatred
We seek Allah’s refuge from them all.”
