The Prophet (saw) said:
“When the son of Adam enters into the morning all of his body parts rebuke the tongue and say: ‘have taqwaa of Allah regarding us. For indeed we are in accordance with you. If you are upright, then we shall be upright, and if you are crooked then we shall be crooked.”
From the greatest of crimes of the tongue and the most despicable, severe, and the most heinous of them is mocking Allah or any of His Names and Attributes; or any of His Ayat, Glorified and Exalted be He; or mocking the Messenger (saw) or anything which has come from Him; or mocking the reward which Allah has prepared for the obedient or the punishment that He has prepared for the disobedient.
Mocking these matters is a nullifier of Al-Islam and disbelief in Allah, the Most High, the Magnificent.
