English translation
5977. Narrated Anas bin Mālik رضي الله عنه : Allāh's Messenger ﷺ mentioned the greatest sins or he was asked about the greatest sins. He said, "To join partners in worship with Allāh; to kill a person whom Allāh has forbidden to kill; and to be undutiful or unkind to the parents." The Prophet ﷺ added, "Shall I inform you of the biggest of the great sins? That is the lying speech (forged statement) or the false witness." Shu'ba (the subnarrator) states that most probably the Prophet ﷺ said, "the false witness."
