Talha bin Abdullah bin Awf says that a woman named Arwa bint Uwais came to me with a group of Quraysh, among whom was Abdur Rahman bin Amr bin Suhail, and she said that Sayyiduna Saeed bin Zaid (may Allah be pleased with him) has included a part of my land into his own land even though it does not belong to him. I want you to go to him and talk to him about this matter. We mounted our rides and set out towards him; at that time he was in his lands in the valley of Aqiq. When he saw us, he said: I understand why you have come. I will tell you a hadith which I myself heard from the Prophet (peace and blessings be upon him): "Whoever takes possession of a piece of land unlawfully, a collar reaching to the seven earths will be placed around his neck on the Day of Resurrection, and whoever is killed while protecting his wealth is a martyr."
