An interesting incident is quoted in Tafsīr al-Mizan from the book Amali. Imrul Qays and another man had a dispute regarding some property. Both of them came to the Holy Prophet (S). He (S) asked Imrul Qays,
“Can you provide two just witnesses to substantiate your claim?”
He replied, “No!”
The Holy Prophet (S) said,
“Then your opponent should take an oath.”
Imrul Qays said, “But what if he swears falsely and acquires my property?”
The Holy Prophet (S) replied,
“If he swears falsely he shall be included among people who will not be eligible for Divine Mercy on the Day of Judgment and Allah shall not purify him of sins. There would be a dreadful punishment for such a man!”
When the litigant heard these statements he was filled with horror and gave up his false claim to the property of Imrul Qays.
