Book Number: 014 / Hadith Number: 3170
Narated By Ubadah ibn as-Samit : The Apostle of Allah (pbuh) used to stand up for a funeral until the corpse was placed in the grave. A learned Jew (once) passed him and said: This is how we do. The Prophet (pbuh) sat down and said: Sit down and act differently from them.
