Hakeemul Ummat Hazrat Moulana Shah Ashraf Ali Thanvi ra said;

“If you were to be the imam to lead in a congregational salah offer very light (short, succinct & manageable) prayers.

This is because there are different kinds of people behind you. Some of them may suffer if you do not do this (i.e. either they may be sick or in a hurry). If you do not care for them they may develop an aversion from praying in congregation.”
