Sahih Muslim Book 4, Hadith Number 850.

Chapter : If the Imam arrives late and there is no danger of an unpleasant happening, another Imam can be appointed to lead the prayer.

Abu Huraira reported: The Messenger of Allah (may peace be upon him) said: Glorification of Allah is for men and clapping of hands is meant for women (if something happens in prayer). Harmala added in his narration that Ibn Shihab told him: I saw some of the scholars glorifying Allah and making a gesture.
