It was narrated that 'Abdullah bin Mas'ood (رضي الله عنه) said:

We asked our Prophet (ﷺ) about walking with the bier and he said: "A rapid walk, for if he (the deceased) was good, he will be hastened (to something good), and if he was otherwise, then away with the people of Hell. The bier should be followed rather than follow, he is not one of its who walks ahead of it.”
