The muslims always beg . . . . . . . . Allah’s help. A. of B. by C. to D. for

The correct answer is: for.

The preposition “for” is used to indicate the purpose or goal of an action. In this case, the Muslims are begging Allah for help.

The other prepositions do not make sense in this context. “Of” is used to indicate possession or origin. “By” is used to indicate means or agency. “To” is used to indicate a destination or goal.

Here are some examples of how the other prepositions can be used:

• The Muslims are proud of their religion.
• The Muslims were persecuted by the Romans.
• The Muslims prayed to Allah.

I hope this helps!
