Sufyan on Men: Who is weaker than a man unable to lower his gaze?

Abu Nu’aym reported: Sufyan al-Thawri, may Allah have mercy on him, said, “A woman will pass by a man and he cannot restrain himself from looking at her lustfully although there is no benefit in it. What could be weaker than this?”

عن أبي نعيم قال سفيان الثوري رحمه الله الْمَرْأَةُ تَمُرُّ بِالرَّجُلِ فَلَا يَمْلِكُ نَفْسَهُ عَنِ النَّظَرِ إِلَيْهَا وَلَا هُوَ يَنْتَفِعُ بِهَا فَأَيُّ شَيْءٍ أَضْعَفُ مِنْ هَذَا
