Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) narrated that the Prophet (peace and blessings be upon him) said: "The greatest of lies is that a person attributes himself to someone other than his father; and the greatest of lies is that a person makes his eyes see in sleep what they did not see (that is, he relates a false dream); and whoever alters the (boundary) markers of land." (Allamah al-Haythami says:) I say: In the Sahih this part of it is reported: "Whoever makes his eyes see what they did not see."
Ahmad recorded it; its chain contains Abu Uthman from Abdullah bin Dinar, and I have not found anyone who has given his biography; the rest of its narrators are the narrators of the Sahih.

Sayyiduna Amr bin Awf (may Allah be pleased with him) narrated that the Prophet (peace and blessings be upon him) said: "Whoever alters the (boundary) markers of land, upon him will be the curse of Allah Almighty and His anger on the Day of Resurrection; Allah Almighty will not accept any obligatory or voluntary worship from him."
Al-Tabarani recorded it in al-Mu'jam al-Kabir; its chain contains Kathir bin Abdullah, who is very da'if (weak), though al-Tirmidhi declared his hadith hasan (good).
