At-Tawbah 9:66

La taAAtathiroo qad kafartumbaAAda eemanikum in naAAfu AAan ta-ifatin minkumnuAAaththib ta-ifatan bi-annahum kanoomujrimeen

Make no excuse; you have disbelieved [i.e., rejected faith] after your belief. If We pardon one faction of you - We will punish another faction because they were criminals.

Make no excuses. You became disbelievers (by mocking at Allah and His Messenger) after you had professed Faith. If We forgive some of you (who repent and believe), We shall punish others (who carry on their hypocrisy), because they were guilty.
