Ottoman travelers pray in a ship while going to Jeddah for Hajj. 

Many of Ottoman sultans and saints would first ask the Beloved Prophet Muhammed (peace be upon him) via prayer for permission to enter Mecca and Medina and only after a spiritual sign of affirmation would they proceed with their journey. This is the level of respect they had for the Beloved Prophet (peace be upon him)- that even after his death, they would seek permission.
