Al-Nawawi reported: Al-Fudayl ibn ‘Iyad, may Allah be pleased with him, said, “Do not feel lonely on the paths of guidance because their people are few, and do not be deceived by the great many who are ruined.”

عن النووي قَالَ الْفُضَيْلُ بْنُ عِيَاضٍ رضي الله عنه لَا تَسْتَوْحِشْ طُرُقَ الْهُدَى لِقِلَّةِ أَهْلِهَا وَلَا تَغْتَرَّ بِكَثْرَةِ الْهَالِكِينَ
