Asma bint Abu Bakr reported,

This is the cloak of the Messenger of Allah ﷺ. It was with Ayesha until she passed away, and when she died I took possession of it. The Prophet ﷺ used to wear it, and we wash it for the sick to seek healing through it.

هذه جبة رسول الله ﷺ، كانت عند عائشة حتى قبضت، فلما قبضت قبضتها، وكان النبي ﷺ يلبسها، فنحن نغسلها للمرضى يستشفى بها.
