How could I take a part of her land, after what I heard from Allah's Messenger (may peace be upon'him)? He (Marwan) said: What did you hear from Allah's Messenger (ﷺ)? He said: I heard Allah's Messenger (ﷺ) say: He who wrongly took a span of land would be made to wear around his neck seven earths. Marwan said: I do not ask any evidence from you after this. He (Sa'id) said: O Allah, make her blind if she has told a lie and kill her in her own land. He (the narrator) said: She did not die until she had lost her eyesight, and (one day) as she was walking in her land, she fell down into a pit and died.
