" الْكَبَائِرُ الشِّرْكُ بِاللَّهِ وَعُقُوقُ الْوَالِدَيْنِ وَقَتْلُ النَّفْسِ وَقَوْلُ الزُّورِ "
It was narrated that 'Ubaidullah bin Abi Bakr said: "I heard Anas say: 'The Messenger of Allah [SAW] said: The major sins are: Associating others with Allah (Shirk), disobeying one's parents, killing a soul (murder) and speaking falsely.'"
