Shaikh Wasiullah Allahabadi (Allah have mercy on him) said,
‘Most frequently the reasons for not developing love of Allah in a murid are,
1. Either listening to the instructions and sayings of Shaikh inattentively or not following them,
2. Not having the love of Shaikh,
3. God-forbid, considering Shaikh to be insignificant,
4. Adulteration in the instructions of the Shaikh through self-opinion (khud raiy).
(Remember) There is no room at all for self-opinion and opposition (of Shaikh) in this path!
