#232 Yahya related to me from Malik from Abu'n Nadr, the mawla of Umar
ibn Ubaydullah, from Malik ibn Abi Amir that Uthman ibn Affan used to
say in khutbas, and he would seldom omit it if he was giving the
khutba, "When the imam stands delivering the khutba on the day of
jumua, listen and pay attention, for there is the same portion for
someone who pays attention but cannot hear as for someone who pays
attention and hears. And when the iqama of the prayer is called,
straighten your rows and make your shoulders adjacent to each other,
because the straightening of the rows is part of the completion of the
prayer." Then he would not say the takbir until some men who had been
entrusted with straightening the rows came and told him that they were
straight. Then he would say the takbir.
