Imam Ja’far al-Sadiq radi Allahu ‘anhu was asked:
Why are our supplications not answered?
Because you do not know the One you are supplicating.
Imam Abu Hanifa (rahimahu Llah) said, emphasizing the importance of sitting at the feet of a spiritual guide and teacher,
If it were not for two years, I would have perished. For two years, I accompanied Imam Ja’far al-Sadiq and I acquired the spiritual knowledge that made me a knower in the Way (i.e. tasawwuf)
