Sahih al-Bukhari 6676, 6677

Narrated `Abdullah:

Allah’s Messenger (ﷺ) said, “If somebody is ordered (by the ruler or the judge) to take an oath, and he takes a
false oath in order to grab the property of a Muslim, then he will incur Allah’s Wrath when he will
meet Him.” And Allah revealed in its confirmation: ‘Verily! Those who purchase a small gain at the
cost of Allah’s covenants and their own oaths.’ (3.77) (The sub-narrator added:) Al-Ash’ath bin Qais
entered, saying, “What did Abu `Abdur-Rahman narrate to you?” They said, “So-and-so,” Al-Ash’ath
said, “This verse was revealed in my connection. I had a well on the land of my cousin (and we had a
dispute about it). I reported him to Allah ‘s Apostle who said (to me). “You should give evidence (i.e.
witness) otherwise the oath of your opponent will render your claim invalid.” I said, “Then he (my
opponent) will take the oath, O Allah’s Messenger.” Allah’s Messenger (ﷺ) said, “Whoever is ordered (by the
ruler or the judge) to give an oath, and he takes a false oath in order to grab the property of a Muslim,
then he will incur Allah’s Wrath when he meets Him on the Day of Resurrection.”
