حَسْبِيَ اللهُ لَا إلَهَ إلَّا هُوَ عَلَيْهِ تَوَكَّلْتُ وَهُوَ رَبُّ العَرْشِ العَظِيمِ [سَبْعَ مَرَّاتٍ]

Allāh is sufficient for me, none has the right to be worshipped except Him, upon Him I rely and He is Lord of the exalted throne. [Seven times]

Reference: Allāh is sufficient for me, none has the right to be worshipped except Him, upon Him I rely and He is Lord of the exalted throne. [Seven times] Ibn al-Sunnī (#71) with a marfūʿ chain and Abū Dāwud (#5081, 4/321) with a mawqūf chain. Shuʿayb and ʿAbd al-Qādir al-Arnā'ūť declared it authentic. Also see _Zād al-Maʿād_ (2/376). Al-Albānī declared it weak. See _Ḍaʿīf Abī Dāwud_.
