Taking Land Unlawfully
Aishah (radi Allahu anha) reported that the Messenger of Allah (sal Allahu alaihi wa sallam) said, “Whoever seizes unlawfully even a hand span of land, a collar measuring seven times (this) land will be placed around his neck on the Day of Resurrection.”
[Sahih al-Bukhari and Muslim]
This Hadith tells us that even a minor injustice to anybody in this world can cause great trouble on the Day of Resurrection.
And Allah Knows Best!
