Narrated Said bin Zaid bin Amr bin Nufail:
That Arwa sued him before Marwan for a right, which she claimed, he had deprived her of. On that Said said, "How should I deprive her of her right? I testify that I heard Allah's Apostle saying, 'If anyone takes a span of land unjustly, his neck will be encircled with it down seven earths on the Day of Resurrection."
