What did the Prophet Muhammad (saw) point at with his hand and describe regarding those who have true belief and those who lack in religious practice?
 Narrated `Uqba bin `Umar and Abu Mas`ud:                     Allah's Apostle pointed with his hand towards Yemen and said, "True Belief is Yemenite yonder (i.e. the Yemenite, had True Belief and embraced Islam readily), but sternness and mercilessness are the qualities of those who are busy with their camels and pay no attention to the Religion where the two sides of the head of Satan will appear. Such qualities belong to the tribe of Rabi`a and Mudar."
