Hadith 1714

'Abdullah bin 'Amr bin Al-As (May Allah be pleased with them) said: The Prophet (PBUH) said, "Of the major sins are: Associating anything in worship with Allah, disobedience to the parents, killing without justification and taking a false oath (intentionally)."

[Al- Bukhari].

Another narration is: A bedouin came to the Prophet (PBUH) and asked him: "O Messenger of Allah, what are the cardinal sins?" He (PBUH) replied, "Associating anything with Allah in worship." The man asked: "(What is) next?" The Messenger of Allah (PBUH) replied, "Al-Yamin Al-Ghamus." He asked: "What do you mean by Al-Yamin Al-Ghamus?" The Messenger of Allah (PBUH) replied, "Swearing falsely to usurp the property of a Muslim."
