Hazrat Mufti Ebrahim Salejee (Daamat Barakaatuhu) mentioned:
Every believer enjoys a connection with Allah Ta‘ala merely on account of his Imaan. Allah Ta‘ala says: “Allah Ta‘ala is the friend of the believers.” Just as a phone gets connected to a network through a sim card, similarly the so-called connecting sim card of a believer is his imaan. Whilst every mu’min enjoys a basic connection with Allah Ta‘ala there are some who work on that connection and make it stronger. They are classified as the Awliyaa, (the special friends of Allah Ta‘ala) regarding whom the Quraan Shareef says: “Indeed the friends of Allah Ta‘ala will not have fear nor will they be grieved.”
