عَن أم سَلمَة قَالَتْ: كَانَ أَحَبُّ الثِّيَابِ إِلَى رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ الْقَمِيصَ. رَوَاهُ التِّرْمِذِيُّ وَأَبُو دَاوُد

Mu'awiya b. Qurra quoted his father as saying

I came to the Prophet with a company of Muzaina who swore allegiance to him, and as his buttons were open I put my hand inside his shirt and felt the seal.Abu Dawud transmitted it.
