The Messenger (sal Allahu alaihi wa sallam) said, “I guarantee a house in the middle of Paradise for a person who avoids lying, even if he was joking.”
[Abu Dawud ~ Hadith Sahih]
This hadith is a continuation of the previous hadith. The Prophet (sal Allahu alaihi wa sallam) here guarantees a house in the middle of paradise for those who avoid lying even if it is a joke. So a Muslim should not prevent himself or herself from this great reward by lying and should strive to always speak the truth.
And Allah Knows Best!
