He leads them in saying du’aa’ together in ‘Arafaat because they do not know how to say du’aa’s properly

On the day of ‘Arafah there is a group who do not know how to say du’aa’s properly, so one of them who knows comprehensive du’aa’s says du’aa’ and they say Ameen behind him. What is the ruling on that?.

Praise be to Allah, and blessings and peace be upon the Messenger of Allah:

There is nothing wrong with that, for example if the person is among people who do not know how to say du’aa’ properly and he leads them in saying du’aa’ and they say Ameen, there is nothing wrong with that. End quote.
