وَمِنْهُم مَّنْ عَاهَدَ اللّهَ لَئِنْ آتَانَا مِن فَضْلِهِ لَنَصَّدَّقَنَّ وَلَنَكُونَنَّ مِنَ الصَّالِحِينَ
[9:75]
And there are those of them who made a covenant with Allah: If He give us out of His grace, we will certainly give alms and we will certainly be of the good.
Amongst them are men who made a covenant with Allah, that if He bestowed on them of His bounty, they would give (largely) in charity, and be truly amongst those who are righteous.
And of them is he who made a covenant with Allah (saying): If He give us of His bounty we will give alms and become of the righteous.
