What did the Prophet Muhammad (saw) do on a rainy and muddy day to train his Mu'adhdhin (may Allah be pleased with him)?
 Narrated `Abdullah bin Al-Harith:                     Once on a rainy muddy day, Ibn `Abbas delivered a sermon in our presence and when the Mu'adhdhin pronounced the Adhan and said, "Haiyi `ala-s-sala(t) (come for the prayer)" Ibn `Abbas ordered him to say 'Pray at your homes.' The people began to look at each other (surprisingly). Ibn `Abbas said. "It was done by one who was much better than I (i.e. the Prophet or his Mu'adh-dhin), and it is a license.'
