Aapka sawal aaik lamba discussion chahta hay. Logoo nay dukanain kholee hain irfan kee.
Aapko mimber per bohat see batain sunnay koo milaingee jiska irfan say koi talluq nahee.
Agha behjat or agha qazi doo mashoor aalim hain.
Irfan kee pehlee orr aakhree step apnay ilm kay mutabiq amal kernaa hay.

As per agha behjat and He extracted from hadees .
the basic of irfan starts as I learnt from namaz at awwal e waqt and to refrain yourself from ZULM
OPPRESSION to other people. Plus there are some ZIKRS to be recited. But first of all you should know what is the meaning of irfan. Your liabilities are,my son, to perform your responsibilities
which is according to the most preferred one, your studies and not to waste your time. Plus giving your parents your sincere services, be kind to them.

Every day while you are going to sleep have an accountability what you have done the whole day
check your 5 senses; eyes, ears, tongue, hands, legs, nose. Did they perform any sin or not? Recite daily surah e yaseen and gift to Imam e Zamana.After every namaz tasbeeh e sayyedah and aayatalkursee.

What is the definition of irfan in your mind?
