Narrated 'Abdullah bin 'Amr: A man asked the Prophet ( ﷺ) , "What sort of deeds or (what qualities of) Islam are good?" The Prophet ( ﷺ ) replied, 'To feed (the poor) and greet those whom you know and those whom you do not Know (See Hadith No. 27 - Narrated Sa'd: Allah's Messenger ( ﷺ) distributed (Zakat) amongst (a group of) people while I was sitting there but Allah's Messenger ( ﷺ ) left a man whom I thought the best of the lot. I asked, "O Allah's Messenger ( ﷺ)! Why have you left that person? By Allah I regard him as a faithful believer." The Prophet ( ﷺ ) 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 Messenger ( ﷺ ), "Why have you left so and so? By Allah! He is a faithful believer." The Prophet ( ﷺ ) again said, "Or merely a Muslim." And I could not help repeating my question because of what I knew about him. Then the Prophet ( ﷺ ) 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." ) Reference : Sahih al-Bukhari 12 In-book reference : Book 2, Hadith 5 USC-MSA web (English) reference : Vol. 1, Book 2, Hadith 12 (deprecated numbering scheme)
