Sayyiduna Ya'la bin Murrah رضي الله عنه narrates that the Messenger of Allah صلى الله عليه وآله وسلم and the Companions went towards a narrow place. He was on his mount. The situation was such that rain was falling from above and there was mud below. Meanwhile, the time for prayer arrived. The Prophet صلى الله عليه وآله وسلم ordered the muezzin, so he gave the adhan and then the iqamah. Then the Messenger of Allah صلى الله عليه وآله وسلم moved forward on his mount and led them in prayer. He صلى الله عليه وآله وسلم indicated for ruku‘ and sujud (bowing and prostration) and for sujud he indicated by lowering himself a little more than for ruku‘.
