Maseehul Ummah, Moulana Muhammad Maseehullah Khan (Rahimahullah) once mentioned,
“It is very easy to become a wali. To become like Hadhrat Junaid Baghdadi (Rahimahullah) and Hadhrat Shibli (Rahimahullah) is also very easy. The doors of prophethood are now closed, hence, no one can become a Nabi, but the doors of wilaayat (becoming the friend of Allah Ta’ala) are not closed. If anyone wants to become a wali, he can become a wali immediately. All one has to do is make firm taubah that you will leave out sins and obey Allah Ta’ala in everything that He has commanded you. This is complete wilaayat. Complete obedience of Allah Ta’ala and complete abstention from sin.”
