49:2 Believers, do not raise your voices above the voice of the Prophet, nor speak loudly to him as you do to one another lest your works should be annulled without your knowledge.
49:3 Those who lower their voice in the presence of the Messenger of Allah are those whose hearts Allah has tested for warding off (evil). They shall receive forgiveness and a great wage.
49:5 If they had patience until you (Prophet Muhammad) went out to them, it would have been better for them. But Allah is the Forgiving and the Most Merciful.
