Abu Wa’il reported: Abdullah ibn Mas’ud, may Allah be pleased with him, said, “Verily, one of you will remain good as long as he fears Allah. If you find doubt within yourself about something, ask a man to cure you from it, but soon you will not be able to find such a person.”

عَنْ أَبِي وَائِلٍ قَالَ عَبْدُ اللَّهِ بْنُ مَسْعُودٍ رَضِيَ اللَّهُ عَنْهُ إِنَّ أَحَدَكُمْ لَنْ يَزَالَ بِخَيْرٍ مَا اتَّقَى اللهَ وَإِذَا شَكَّ فِي نَفْسِهِ شَيْءٌ سَأَلَ رَجُلًا فَشَفَاهُ مِنْهُ وَأَوْشَكَ أَنْ لَا تَجِدُوهُ
