Islam began as something strange 0

  النبي صلى الله عليه وسلم قال: بدأ الإسلام غريباً، وسيعود غريباً كما بدأ، فطوبى للغرباء، الذين يُصلحون ما أفسد الناس

The Prophet peace be upon him said: Islam began as something strange and will revert to being strange as it began, so give glad tidings to the strangers, who are repairing the corrupted people.
