64 . The hypocrites fear lest a Sûrah (chapter of the Qur'ân) should be revealed about them, showing them what is in their hearts. Say: "(Go ahead and) mock! But certainly Allâh will bring to light all that you fear." (At-Tawbah 9:64)

65. If you ask them (about this), they declare: "We were only talking idly and joking." Say: "Was it at Allâh, and His Ayât (proofs, evidences, verses, lessons, signs, revelations, etc.) and His Messenger (SAW) that you were mocking?" (At-Tawbah 9:65)

66. Make no excuse; you have disbelieved after you had believed. If We pardon some of you, We will punish others amongst you because they were Mujrimûn (disbelievers, polytheists, sinners, criminals, etc.). (At-Tawbah 9:66)
