Qur'an 9:75

۞ وَمِنْهُم مَّنْ عَـٰهَدَ ٱللَّهَ لَئِنْ ءَاتَىٰنَا مِن فَضْلِهِۦ لَنَصَّدَّقَنَّ وَلَنَكُونَنَّ مِنَ ٱلصَّـٰلِحِينَ

“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."”
