Jabir ibn 'Abdullah · The Book of Knowledge

He who introduced some good practice in Islam which was followed after him (by people) he would be assured of reward like one who followed it, without their rewards being diminished in any respect. And he who introduced some evil practice in Islam which had been followed subsequently (by others), he would be required to bear the burden like that of one who followed this (evil practice) without their's being diminished in any respect.

The servant does not introduce good practice which is followed after him.... The rest of the hadith is the same.
