At Tawbah, 75 Ayah
9:75
۞ وَمِنۡهُم مَّنۡ عَٰهَدَ ٱللَّهَ لَئِنۡ ءَاتَىٰنَا مِن فَضۡلِهِۦ لَنَصَّدَّقَنَّ وَلَنَكُونَنَّ مِنَ ٱلصَّٰلِحِينَ ٧٥
Wa Minhum Man `Āhada Al-Laha La'in 'Ātānā Min Fađlihi Lanaşşaddaqanna Wa Lanakūnanna Mina Aş-Şāliĥīna
And among them are those who made a covenant with Allah, [saying], "If He should give us from His bounty, we will surely spend in charity, and we will surely be among the righteous."
