Al-Imām al-Bukhārī - upon whom be mercy - narrates: Zakariyyā related to us; he said: Abū Usāmah related to us, from Hishām ibn ‘Urwah, from his father,

from our mother ‘Ā’ishah (may Allāh Almighty be content with her), who said: The Messenger of Allāh ﷺ said: “Indeed, you have been granted permission to go out in order to fulfil your needs.”

Hishām - upon whom be mercy - clarified: That is, for relieving oneself.
