The Bedouins Are The Worst In Disbelief

Question :

Some of my friends and I disagreed about the meaning of this verse:
"The Bedouins are the worst in disbelief and hypocrisy".

What is its correct meaning? Why are Bedouins thus described in the Qur'an? And regarding what circumstances was this verse revealed?

Answer:

Bedouins are people who live in the desert, moving from place to place, looking for places with rain for their livestock, from which they derive their living. Because they hardly come near villages and cities, they are for the most part ignorant; hence faith is weak in their hearts. Therefore they are worse in disbelief and hypocrisy than city-dwellers. Allâh Almighty says:
"The Bedouins say: We believe. Say: You believe not but you only say, "We have surrendered (in Islam), for faith has not yet entered your hearts."

But even still, Allâh Almighty say that there some of them:
"Who believe in Allah and the Last Day, and look upon what they spend in Allah's Cause as a means of nearness to Allah, and a cause of receiving the Messenger's invocations."

In another sense they are purer than people of the city: they are not as susceptible to the doubts and worldly lusts that are common to city life. And Allâh Almighty knows best.
