The renunciation giving up quitting forsaking abnegation or dereliction of those things which are the Outsiders of Allah for the sake of Allah. Tark of Dunya (World) is Sunnat and forsaking the Nafs is recommendatory (Mustahib) and renunciation of Satan is essential (Waajib) (P05 Didaar Bakhsh Khurd). And he has Hairat because of the reason that Hairat gives birth to the Tark (abnegation) of Dunya (World). Tark of Dunya (World) is Welfare (and virtue) all over. (P209 Muhik ul Faqar Klaan). Also see P72 Fazal ul Liqaa P168 Muhik ul Faqar Klaan.
