عَنْ أَسْمَاءَ بِنْتِ يَزِيدَ اَلْأَنْصَارِيَّةَ رضى اَللَّهُ عَنْهَا قَالَتْ: كَانَ كُمُّ قَمِيصِ رَسُولِ اللهِ صَلَّى اللَّه عَلَيْهِ وَسَلَّمَ إِلَى الرُّسْغِ.((رَوَاهُ أَبُو دَاوُد وَالتِّرْمِذِيّ))
Asma' bint Yazid (May Allah be pleased with her) reported: The sleeves of the Messenger of Allah (ﷺ)'s Qamees reached down to his wrists. [Abu Dawud and At-Tirmidhi].
