Sahih al-Bukhari Book 70, Hadith 4
I was a boy under the care of Allah's Messenger (ﷺ) and my hand used to go around the dish while I was
eating. So Allah's Messenger (ﷺ) said to me, 'O boy! Mention the Name of Allah and eat with your right
hand, and eat of the dish what is nearer to you." Since then I have applied those instructions when
eating.
Once while I was in a state of fatigue (because of severe hunger), I met 'Umar bin Al-Khattab, so I asked him to recite a verse from Allah's Book to me. He entered his house and interpreted it to me. (Then I went out and) after walking for a short distance, I fell on my face because of fatigue and severe hunger. Suddenly I saw Allah's Apostle standing by my head. He said, "O Abu Huraira!" I replied, "Labbaik, O Allah's Messenger (ﷺ), and Sadaik!" Then he held me by the hand, and made me get up. Then he came to know what I was suffering from. He took me to his house, and ordered a big bowl of milk for me. I drank thereof and he said, "Drink more, O Abu Hirr!" So I drank again, whereupon he again said, "Drink more." So I drank more till my belly became full and looked like a bowl. Afterwards I met 'Umar and mentioned to him what had happened to me, and said to him, "Somebody, who had more right than you, O 'Umar, took over the case. By Allah, I asked you to recite a Verse to me while I knew it better than you." On that Umar said to me, "By Allah, if I admitted and entertained you, it would have been dearer to me than having nice red camels.
Who was the son of Um Salama, the wife of the Prophet: Once I ate a meal with Allah's Messenger (ﷺ) and I was eating from all sides of the dish. So Allah's Messenger (ﷺ) said to me, "Eat of the dish what is nearer to you."
