Gleanings — Paragraph 700

اشتعل بنار الحبّ وزیّن بطراز الانقطاع یشتعل بذکره العباد إنّ ربّک لهو العلیم الخبیر طوبی لمن سمع النّدآء وأجاب إنّه من المقرّبین...
Translation
If he be kindled with the fire of His love, if he forgoeth all created things, the words he uttereth shall set on fire them that hear him. Verily, thy Lord is the Omniscient, the All-Informed. Happy is the man that hath heard Our voice, and answered Our call. He, in truth, is of them that shall be brought nigh unto Us.
