وَعَنِ ابْنِ عَبَّاسٍ
قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «الْأَمْرُ ثَلَاثَةٌ: أَمْرٌ بَيِّنٌ رُشْدُهُ فَاتَّبِعْهُ وَأَمْرٌ بَيِّنٌ غَيُّهُ فَاجْتَنِبْهُ وَأَمْرٌ اخْتُلِفَ فِيهِ فَكِلْهُ إِلَى اللَّهِ عَزَّ وَجل)
a matter whose right guidance is clear, which you must follow; a matter whose error is clear, which you must avoid; and a matter about which there is a difference of opinion, which you must entrust to God.
