Asmā' bint Yazīd (may Allah be pleased with her) reported: The sleeves of the shirt of the Messenger of Allah (may Allah's peace and blessings be upon him) reached down to his wrists.
شرح الحديث :
The length of the sleeves of the Prophet (may Allah's peace and blessings be upon him) reached down to the joint that is between the palm and the forearm. This narration has some weakness, but there is no other narration to contradict it.
