Verily, one of the worst lies is to claim falsely...

Hadith of the day 

Allah's Messenger (ﷺ) said, "Verily, one of the worst lies is to claim falsely to be the son of someone other than one's real father, or to claim to have had a dream one has not had, or to attribute to me what I have not said."

 [Sahih al-Bukhari 3509]
