2 Al-Baqarah 41

2:41 Verse 41 asks the Israelites not to be the first to deny the Holy Qur'an, although being a disbeliever is in itself the ultimate sin, whether one be the first or the last. The verse, in fact, suggests that the man who is the first to deny and disbelieve will not only incur the sin of his own denial but also bear the additional burden of the sin of misleading all those who follow his example; and will thus have to undergo a multiple punishment. It follows from here that the man who is in any way responsible for others falling into any kind of sin will have to bear the burden of this sin along with the sinners; similarly, the man who in some way helps others to do a good deed will receive a reward for it along with them. Several verses of the Holy Qur'an and the ahadith of the Holy Prophet ﷺ repeatedly stress this point.
