Concealing testimony

A: It is not permissible to conceal testimony; whoever does so is wrongful and sinful and should repent to Allah (Exalted be He). Allah states: And the witnesses should not refuse when they are called (for evidence). And And conceal not the evidence for he, who hides it, surely his heart is sinful. And Allâh is All-Knower of what you do. May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
