عَنِ ابْنِ عَبَّاسٍ رَضِيَ اللَّهُ عَنْهُمَا أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ قَالَ ((لَا تَفْتَخِرُوا بِآبَائِكُمُ الَّذِينَ مَاتُوا فِي الْجَاهِلِيَّةِ فَوَالَّذِي نَفْسِي بِيَدِهِ لَمَا يُدَهْدِهُ الْجُعَلُ بِمَنْخِرَيْهِ خَيْرٌ مِنْ آبَائِكُمُ الَّذِينَ مَاتُوا فِي الْجَاهِلِيَّةِ))
It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) that the Noble Prophet (peace and blessings be upon him and his family) said: Do not take pride in your forefathers who died in the age of ignorance. By the One in Whose hand is my soul! The dung beetle (black insect) that rolls things with its nose is better than those ancestors of yours who died in the age of ignorance.
