Jihad (Kitab Al-Jihad)
Dawud :: Book 14 : Hadith 2614
Narrated Abbad ibn Shurahbil:
I suffered from drought; so I entered a garden of Medina, and rubbed an ear-corn. I ate and carried in my garment. Then its master came, he beat me and took my garment. He came to the Apostle of Allah (peace_be_upon_him) who said to him: You did not teach him if he was ignorant; and you did not feed him if he was hungry. He ordered him, so he returned my garment to me, and gave me one or half a wasq (sixty or thirty sa's) of corn.
