Imam repeating some verses that speak of mercy or punishment
Question

                What is the ruling on the imam repeating some verses that speak of mercy or punishment?.
Praise be to Allah.
    I do not know of anything wrong with that, because it 
    encourages the people to ponder and focus and benefit. It was narrated that 
    the Prophet  (peace and blessings of Allaah be upon him) repeated the 
    verse (interpretation of the meaning): “If You punish them, they are Your 
    slaves, and if You forgive them, verily, You, only You, are the All‑Mighty, 
    the All‑Wise” [al-Maa'idah 5:118] several times.  

    To sum up: if it is done for a good reason and not for the 
    purpose of showing off, then there is nothing wrong with it, but if he 
    thinks that repeating it may annoy them or result in disturbing sounds such 
    as weeping, then it is better not to do that, so that there will not be any 
    distraction. But if repeating it will only lead to pondering and proper 
    focus on the prayer, then it is all good. End quote.
