"When I was a boy, I used to throw stones at our date-palm trees" - or he said: "the date-palm trees of the Ansar." I was brought to the Prophet (ﷺ) and he said: 'O boy' - (one of the narrators) Ibn Kasib said: He said: 'O my son - why are you throwing stones at the date-palm trees?' I said: 'So I can eat.' He said: 'Do not throw stones at the date-palm trees. Eat from what falls to the ground from them.' Then he patted me on the head and said: 'O Allah give him enough to eat.'”
Sunan Ibn Majah Book 12, Hadith 163
← Previous Hadith “I heard 'Abbad bin Shurahbil, a man from Banu Ghubar, say: ‘We suffered a year of famine, and I came to Al-Madinah. I came to one of its gardens and took an ear of corn, I rubbed it, ate some and put the rest in my garment. The owner of the garden came and beat me and took my garment. I came to the Prophet (ﷺ) and told him (what had happened). He said to the man: "You did not feed him when he was hungry and you did not teach him when he was ignorant."' Then the Prophet (ﷺ) told him to give back his garment and ordered that a Wasq or half a Wasq of food be brought to him."

Sunan Ibn Majah Book 12, Hadith 162 Next Hadith → "When you come to a shepherd, call him three times. If he answers (all well and good), otherwise drink (milk from the flock) without taking advantage. And when you come to a garden call the owner of the garden three times. If he answers (all well and good), otherwise eat (from the produce of the garden) without taking advantage."
