What did the Prophet Muhammad (saw) do when the roof of the house started leaking during prayer time?
 Narrated Abu Sa`id Al-Khudri:                     A cloud came and it rained till the roof started leaking and in those days the roof used to be of the branches of date-palms. Iqama was pronounced and I saw Allah's Apostles prostrating in water and mud and even I saw the mark of mud on his forehead.
