On the Day of Judgement, there will be people who will bear not only the full burdens of their sins, but also some burdens of others whom they misled!

Verses 24-25 of Chapter 16:

And when they are asked, "What is it that your Lord has sent down?" they say these are mere fairy tales of the ancients.They say such things so that they should bear the full brunt of their own burdens on the Day of Resurrection together with some of the burdens of those whom they are leading astray in their ignorance. Behold! what a heavy responsibility they are taking on themselves!
