Al-Ma'idah 5:105

Ya ayyuha allatheena amanooAAalaykum anfusakum la yadurrukum man dallaitha ihtadaytum ila Allahi marjiAAukumjameeAAan fayunabbi-okum bima kuntum taAAmaloon

O you who have believed, upon you is [responsibility for] yourselves. Those who have gone astray will not harm you when you have been guided. To Allāh is your return all together; then He will inform you of what you used to do.

O you who believe, take care of your own selves. The one who has gone astray cannot harm you, if you are on the right path. To Allah all of you have to return. Then He will tell you what you have been doing.
