What ? Islam is mad, over a snub; The tribe of Dan rejected their God and their rejection continues to this day. They will continue to reject God in the tribulation but they will turn to God at the end of the millennial kingdom; Dan shall be a serpent in the way,
A horned snake in the path,
That bites the horse’s heels,
So that his rider falls backward.
For Your salvation I wait, O LORD Genesis 49:16-18
