Naseehah that is against Islam is not to be followed

Giving naseehah is part of Sharia. Therefore, if someone gives advice to leave a deen demanded by the Sharia or to perform a forbidden deed, then it is not called naseehah. The one giving such should quit doing that and the one being advised should not accept it. For instance, if someone tells you to shave your beard, to expose some part of the body by taking off the hijab, to shake hands with women on job interviews, to date the girl you are interested in, to take a job at a gas station that sells alcohol, or to go see the latest movie, then you should not obey. These matters are not counted as naseehah which the Prophet (sallAllahu 'alaihi wa sallam) made part of the religion.
