Mishkat al-Masabih 30 Fine Qualities كتاب المناقب 94

وَعَنْ عَائِشَةَ أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ: «يَا عُثْمَانُ إِنَّهُ لَعَلَّ اللَّهَ يُقَمِّصُكَ قَمِيصًا فَإِنْ أَرَادُوكَ عَلَى خَلْعِهِ فَلَا تَخْلَعْهُ لَهُمْ» . رَوَاهُ التِّرْمِذِيُّ وَابْنُ مَاجَهْ وَقَالَ التِّرْمِذِيُّ فِي الحَدِيث قصَّة طَوِيلَة

`A’isha reported the Prophet as saying, “Perhaps God will clothe you with a shirt, `Uthman, and if the people want you to take it off, do not take it off for them[*].” * Mirqat , 5:558, interprets this as referring to the Caliphate which he is told not to resign even though the people should wish him to abdicate. Tirmidhi and Ibn Majah transmitted it, Tirmidhi saying the tradition contains a long story.
