Q: There is an engineer in a road pavement company who sometimes alters the laboratory results of the soil compaction tests and the asphalt quality tests. Does this man fall under those mentioned in the Hadith where the Prophet (peace be upon him) said, "Anyone who deceives us is not one of us.'' ? In which case, is this man's salary unlawful? Can he be free from any blame if he does such acts to please his superiors even though he abhors doing so? Please give us your Fatwa (legal opinion issued by a qualified Muslim scholar) and may Allah reward you good!

A: It is not permissible for this engineer to change the test results of soil samples or asphalt for worse ones, even if his superiors give him a direct order to do so, as this is a form of prohibited deception. It is confirmed in Sahih (book of authentic Hadith) by Muslim that the Prophet (peace be upon him) said, "Anyone who deceives us is not one of us." In another narration, he (peace be upon him) said, "Anyone who deceives is not one of us.'' (Part No. 15; Page No. 138) May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
