حَدَّثَنَا فَرْوَةُ بْنُ أَبِي الْمَغْرَاءِ، قَالَ: حَدَّثَنَا عَلِيُّ بْنُ مُسْهِرٍ، عَنْ هِشَامِ بْنِ عُرْوَةَ، عَنْ أَبِيهِ قَالَ: كُنْتُ جَالِسًا عِنْدَ مُعَاوِيَةَ، فَحَدَّثَ نَفْسَهُ، ثُمَّ انْتَبَهَ فَقَالَ: لاَ حِلْمَ إِلاَّ تَجْرِبَةٌ، يُعِيدُهَا ثَلاثًا.
It is narrated from Urwah (may Allah have mercy on him) that I was sitting with Sayyiduna Muawiyah (may Allah be pleased with him) when a thought crossed his mind, then he composed himself and said: Forbearance comes only through experience. He repeated this statement three times.
