Question

which are the worsts sins in the eyes of the holy prophet?​

Answer 1

Narrated by Ḥaḍrat Abū Bakr Siddīq, Allāh be pleased with him: Said the Prophet of Allāh (peace of Allāh and His blessings be on him): “Shall I apprise you of the three great sins?” We said, ‘Aye, O Prophet of Allāh.’ He said: “Hearken! The biggest sin is setting up equals to All āh and then disobedience of parents and neglect of duty to them,” and, leaving the cushion he was leaning against, and sitting up in a roused manner, he said with great force, “Hearken! And lying,” and he repeated it so many times that we wished he had left it off at that and not strained himself so much. (Bukh ārī)
