He answered, “A wicked and adulterous generation asks for a sign! But none will be given it except the sign of the prophet Jonah. For as Jonah was three days and three nights in the belly of a huge fish, so the Son of Man will be three days and three nights in the heart of the earth.

Matthew 12:39–40

Friday night to Sunday morning is not what he said, they might be lying to you. Ask him yourself, show them your face Most High.
