Abū Hātim Al-Bustī رحمه الله stated:

“Whoever becomes busy with the faults of the people ignoring the faults of himself: His heart becomes blind, his body becomes fatigued and he does not have the ability the abandon his own faults.”

[Rawdah Al-‘Uqalā 125]

قـال أبو حاتم البستي رحمه الله

من اشتغل بعيوب الناس عن عيوب نفسه عمي قلبه وتعب بدنه وتعذر عليه ترك عيوب نفسه

[روضة العقلاء ١٢٥]
