حَدَّثَنَا سَعْدُ بْنُ حَفْصٍ، حَدَّثَنَا شَيْبَانُ، عَنْ مَنْصُورٍ، عَنِ الْمُسَيَّبِ، عَنْ وَرَّادٍ، عَنِ الْمُغِيرَةِ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ ‏"‏ إِنَّ اللَّهَ حَرَّمَ عَلَيْكُمْ عُقُوقَ الأُمَّهَاتِ، وَمَنْعَ وَهَاتِ، وَوَأْدَ الْبَنَاتِ، وَكَرِهَ لَكُمْ قِيلَ وَقَالَ، وَكَثْرَةَ السُّؤَالِ، وَإِضَاعَةَ الْمَالِ ‏"‏‏.‏

Narrated Anas bin Malik

Allah's Messenger (ﷺ) mentioned the greatest sins or he was asked about the greatest sins. He said, "To join partners in worship with Allah; to kill a soul which Allah has forbidden to kill; and to be undutiful or unkind to one's parents." The Prophet (ﷺ) added, "Shall I inform you of the biggest of the great sins? That is the forged statement or the false witness." Shu`ba (the sub-narrator) states that most probably the Prophet said, "the false witness."
