حَسْبِـيَ اللّهُ لا إلهَ إلاّ هُوَ عَلَـيهِ تَوَكَّـلتُ وَهُوَ رَبُّ العَرْشِ العَظـيم. (سبع مرات
Ḥasbiyallāhu lā ilāha illā huwa `alayhi tawakkalt, wa huwa Rabbu ‘l-`Arshi ‘l-'Aẓīm.
Allah is sufficient for me. There is none worthy of worship but Him. I have placed my trust in Him, He is Lord of the Majestic Throne. (Recite seven times in Arabic.)
Allah will grant whoever recites this seven times in the morning or evening whatever he desires from this world or the next, Ibn As-Sunni (no. 71), Abu Dawud 4/321. Both reports are attributed directly to the Prophet (ﷺ) j§ (Marfu1). The chain of transmission is sound (Sahih). Ibn As-Sunni.
