3690. It was narrated that Al-Ĥârith bin Miskîn said, it being read to him while I was listening: "From Sufyân, from Az-Zuhri, from 'Ubaidullâh bin 'Abdullâh, from Ibn 'Abbâs, that Sa'd bin 'Ubâdah consulted the Prophet ﷺ about a vow which his mother had to fulfill, but she died before doing so. The Messenger of Allâh ﷺ said: 'Fulfill it on her behalf.'" (Sahīh)
