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

And of them are some who made a covenant with Allah (saying): "If He bestowed on us of His Bounty, we will verily, give Sadaqah (Zakat and voluntary charity in Allah's Cause) and will be certainly among those who are righteous." - Muhammad Taqi-ud-Din al-Hilali and Muhammad Muhsin Khan (English)
