"حَسْبِيَ اللهُ لَآ إِلَهَ إِلَّا هُوَ عَلَيْهِ تَوَكَّلْتُ وَهُوَ رَبُّ الْعَرْشِ الْعَظِيمِ".

Hasbiyallaahu laa 'ilaaha 'illaa Huwa 'alayhi tawakkaltu wa Huwa Rabbul-'Arshil-'Adheem .

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 .)

Reference:
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 j§ (Marfu1). The chain of transmission is sound (Sahih). Ibn As-Sunni.

Note:
By morning it refers to after Fajr until about ten minutes before duhr and by evening, one may read it after 'asr ( according to some scholars) or maghrib ( according to other scholars).
