Hadith 9944ـ يُونُسُ عَنْ عَبْدِ الله بْنِ سِنَانٍ قَالَ سَمِعْتُ أَبَا عَبْدِ الله (عَلَيهِ السَّلام) يَقُولُ إِنَّ مِنَ الْكَبَائِرِ عُقُوقَ الْوَالِدَيْنِ وَالْيَأْسَ مِنْ رَوْحِ الله وَالأمْنَ لِمَكْرِ الله وَقَدْ رُوِيَ أَنَّ أَكْبَرَ الْكَبَائِرِ الشِّرْكُ بِالله.
4. Yunus has narrated from ‘Abd Allah ibn Sinan who has said the following: “I heard Abu ‘Abdillah (a.s.) saying, ‘Of the major sins are disregard of good relation with parents, despair for the mercy of Allah, feeling safe from the punishment of Allah and it is narrated that the biggest of the major sins is to consider things as partners of Allah.’”
