Allah, the Exalted, said (in Surah Hud) «لا عاصم اليوم من امز الله», the meaning of «عاصم» is "one who prevents." Mujahid said regarding what is mentioned in Surah Ya-Sin «وجعلنا من بين ايديهم سدا», meaning "We have placed a barrier before them from accepting the truth, so they wander blindly in their error (pit)." And the word «دساها» in Surah ash-Shams means "He led astray."
Narrated Abu Sa`id Al-Khudri: That the Prophet said, "No Caliph is appointed but has two groups of advisors: One group advises him to do good and urges him to adopt it, and the other group advises him to do bad and urges him to adopt it; and the protected is the one whom Allah protects."

´It was narrated from Abu Saeed tht the Messenger of Allah said:` "Allah never sends a prophet or appoints a Khalifah but he has two groups of advisers: A group that tells him to do good and a group that tells him to do evil and urges him to do it. And the one who is truly protected is the one who is protected by Allah, the Mighty and Sublime."
Hafiz Muhammad Ameen
This matter is not exclusive to the Prophet or the Caliph; every person encounters this situation. He meets both good companions and bad ones. Fortunate is the person who is dominated by good companions and advisors, and this is not possible without the mercy of Allah, the Exalted. And unfortunate is the person who remains under the influence of bad companions and advisors.
