Hakeemul Ummat Hazrat Mawlana Ashraf Ali Thanawi ra said:

“It is an established practice of Allah SWT (‘adatullah) in regards to the individual who after taking the path of ahlullah (tareeq) forsakes it, either due to laziness or by rejecting it (in principle), he is most of the times denied the tawfeeq (opportunity) of returning back to it.  He remains redundant.”

Allah SWT save us all from this.
