Abbad bin Tamim narrates from his uncle that when the Messenger of Allah (peace be upon him) went out for the prayer of Istisqa (prayer for rain), he faced the Qiblah and turned his back to the people. He turned his cloak inside out, led them in two rak'ahs, and recited (Qur'an) in them. And he recited aloud in them.
