question #1 Sahih Muslim 604a-b, Book 5, Hadith 200 : What is the significance of waiting for the Imam before standing for prayer after the Iqama is pronounced?

The Messenger of Allah (ﷺ) said: When the Iqama is pronounced do not get up till you see me Ibn Hatim was in doubt whether it was said:” When the Iqama is pronounced” or” When call is made”.
