Ubaidullah bin Abu Bakr (RA) said: I heard Anas bin Malik (RA) saying: The Messenger of Allah ( صلی اللہ علیہ وسلم ) talked about the major sins, or he was asked about the major sins. Upon this he observed: Associating anyone with Allah, killing of a person, disobedience to parents. He (the Holy Prophet ( صلی اللہ علیہ وسلم ) further) said: Should I not inform you about the gravest of the major sins, and (in this connection) observed: False utterance or false testimony. Shu'bah said. It was most probably" false testimony".
