Sahih al-Bukhari 4549, 4550
Narrated Abu Wail:
`Abdullah bin Masud said, "Allah's Messenger (ﷺ) said, 'Whoever takes an oath when asked to do so, in 
which he may deprive a Muslim of his property unlawfully, will meet Allah Who will be angry with 
him.' So Allah revealed in confirmation of this statement:--"Verily! Those who Purchase a small gain 
at the cost of Allah's Covenant and oaths, they shall have no portion in the Hereafter..." (3.77) Then 
entered Al-Ash'ath bin Qais and said, "What is Abu `Abdur-Rahman narrating to you?" We replied, 
'So-and-so." Al-Ash'ath said, "This Verse was revealed in my connection. I had a well in the land of 
my cousin (and he denied my, possessing it). On that the Prophet (ﷺ) said to me, 'Either you bring forward 
a proof or he (i.e. your cousin) takes an oath (to confirm his claim)' I said, 'I am sure he would take a 
(false) oath, O Allah's Messenger (ﷺ).' He said, 'If somebody takes an oath when asked to do so through 
which he may deprive a Muslim of his property (unlawfully) and he is a liar in his oath, he will meet 
Allah Who will be angry with him.' "
