وَمَنْ لَمْ يَنْفَعْهُ اللهُ بِالْبَلاَءِ وَالتَّجَارِبِ لَمْ يَنْتَفِعْ بِشَيْء مِنَ الْعِظَةِ، وَأَتَاهُ الْتَّقْصِيرُ مِنْ أَمَامِه، حَتَّى يَعْرِفَ مَا أَنْكَرَ، وَيُنْكِرَ مَا عَرَفَ. وَإنَّمَا النَّاسُ رَجُلاَنِ: مُتَّبِعٌ شِرْعَةً، وَمُبْتَدِعٌ بِدْعَةً، لَيْسَ مَعَهُ مِنَ اللهِ سُبْحَانَهُ بُرْهَانُ سُنَّة، وَلاَ ضِياءُ حُجَّة.
He whom Allāh does not allow benefit from trials and experience cannot benefit from preaching. He will be faced with losses from in front, so that he will approve what is bad and disapprove what is good. People are of two categories - the follower of the sharī‘ah (religious laws), and the follower of the innovations to whom Allāh has not given any testimony by way of sunnah or the light of any plea.
