Anas on Muhlikat: You think your sins are minor, but we did not

Ghaylan reported: Anas ibn Malik, may Allah be pleased with him, said, “Verily, you indulge in bad deeds that are as insignificant as a hair in your eyes, yet in the time of the Messenger of Allah, peace and blessings be upon him, we considered them mortal sins.”

Abu Abdullah said, “By that he means they are destructive vices.”

عَنْ غَيْلاَنَ عَنْ أَنَسٍ رَضِيَ اللَّهُ عَنْهُ قَالَ إِنَّكُمْ لَتَعْمَلُونَ أَعْمَالًا هِيَ أَدَقُّ فِي أَعْيُنِكُمْ مِنْ الشَّعَرِ إِنْ كُنَّا لَنَعُدُّهَا عَلَى عَهْدِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ مِنْ الْمُوبِقَاتِ

قَالَ أَبُو عَبْدِ اللَّهِ يَعْنِي بِذَلِكَ الْمُهْلِكَاتِ
