Journey with Quran: Give charity for the sake of Allah.

Surah Al Taubah verse 75

وَمِنْهُم مَّنْ عَاهَدَ اللَّـهَ لَئِنْ آتَانَا مِن فَضْلِهِ لَنَصَّدَّقَنَّ وَلَنَكُونَنَّ مِنَ الصَّالِحِينَ

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."
