At-Tawbah · Ayah 75
وَمِنْهُم مَّنْ عَٰهَدَ ٱللَّهَ لَئِنْ ءَاتَىٰنَا مِن فَضْلِهِۦ لَنَصَّدَّقَنَّ وَلَنَكُونَنَّ مِنَ ٱلصَّٰلِحِينَ
And among them are those who made a covenant with Allāh, [saying], "If He should give us from His bounty, we will surely spend in charity, and we will surely be among the righteous."
