It was narrated that Al-Harith bin Miskin said, it being read to him while I was listening: "From Sufyan, from Az-Zuhri, from Ubaidullah bin Abdullah, from Ibn Abbas, that Sad bin Ubadah consulted the Prophet (صلی اللہ علیہ وسلم) about a vow which his mother had to fulfill, but she died before doing so. The Messenger of Allah (صلی اللہ علیہ و آلہ سلم) said: Fulfill it on her behalf.
