"O you who believe! Do not render in vain your Sadaqah (charity) by reminders of your generosity or by injury, like him who spends his wealth to be seen of men, and he does not believe in Allaah, nor in the Last Day, His likeness is the likeness of a smooth rock on which is a little dust; on it falls heavy rain which leaves it bare, They are not able to do anything with what they have earned, And Allaah does not guide the disbelieving people." [Al-Baqarah (2):264]

Narrated Sa'd:

Allah's Apostle distributed (Zakat) amongst (a group of) people while I was sitting there but Allah's Apostle left a man whom I thought the best of the lot. I asked, "O Allah's Apostle! Why have you left that person? By Allah I regard him as a faithful believer." The Prophet commented: "Or merely a Muslim." I remained quiet for a while, but could not help repeating my question because of what I knew about him. And then asked Allah's Apostle, "Why have you left so and so? By Allah! He is a faithful believer." The Prophet again said, "Or merely a Muslim." And I could not help repeating my question because of what I knew about him. Then the Prophet said, "O Sa'd! I give to a person while another is dearer to me, for fear that he might be thrown on his face in the Fire by Allah." [The Book of Faith Volume 1, Book 2, Hadeeth 26]
