Jabir said the Prophet decreed the right to buy neighbouring property applicable to everything which is not divided, but when boundaries were fixed and separate roads made there was no option.
He told of hearing God’s Messenger say, “If anyone wrongly takes a span of land God who is great and glorious will make him dig it till he gets to the end of seven earths, and then he will have it tied round his neck till the day of resurrection until men are judged.”
He said that God’s Messenger decreed the right of option regarding everything which is shared, whether a dwelling or a garden, when it had not been divided. It is not lawful to sell before informing one’s partner who may take it or let it go as he wishes ; but if he sells without informing him, he has the greatest right to it.
Ya'la b. Murra told of hearing God’s Messenger say, “If anyone seizes land to which he has no right he will be made to carry its earth at the resurrection.”
