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."
