Sunan Ibn Majah Book 16, Hadith 13
“A man from among the Ansar Came and said: 'O Messenger of Allah (ﷺ), why do I see that your color has changed?' He said: 'Hunger.' So the Ansari went to his dwelling, but he did not find anything in his dwelling, so he went out looking, and he found a Jew watering his date-palm trees. The Ansari stipulated that he would not take any dates that were black (rotten), hard and dried out or inferior, and he would only take good quality dates. He earned nearly two Sa's (of dates), and he brought it to the Prophet (ﷺ).”
“I used to draw water, one bucket for a date, and I stipulated that they should be good quality, dried dates.”
“The Messenger of Allah (ﷺ) forbade Muhaqalah and Muzabanah, and said: 'Only three may cultivate: A man who has land which he cultivates a man who was given some land and cultivates what he was given; and a man who takes land on lease for gold or silver.' ”
