Sahih al-Bukhari Book 46, Hadith 15
The Prophet (ﷺ) said, "Whoever takes a piece of the land of others unjustly, he will sink down the seven
earths on the Day of Resurrection."
That there was a dispute between him and some people (about a piece of land). When he told `Aisha about it, she said, "O Abu Salama! Avoid taking the land unjustly, for the Prophet (ﷺ) said, 'Whoever usurps even one span of the land of somebody, his neck will be encircled with it down the seven earths."
"We were in Medina with some of the Iraqi people, and we were struck with famine and Ibn Az- Zubair used to give us dates. Ibn `Umar used to pass by and say, "The Prophet (ﷺ) forbade us to eat two dates at a time, unless one takes the permission of one's companions."
