Du'a of reliance on Allah

حَسۡبُنَا ٱللَّهُ وَنِعۡمَ ٱلۡوَكِيلُ، نِعۡمَ ٱلۡمَوۡلَىٰ وَنِعۡمَ ٱلنَّصِيرُ

Hasbunallahu wa ni'mal-wakilu, ni'mal-mawla wa ni'man-nasir

Allah is Sufficient for us! Most Excellent is He in Whom we trust. A Transcendent Patron, a Transcendent Helper.

Qur'an 3:173 and 8:40 (two clauses joined)
