From Muhammad bin Syu'aib and Said bin Abdil Aziz said, "During the reign of Mu'awiyah there was a long dry season. Mu'awiyah went out for Istisqa prayer with the community. When they arrived at the place to be used for Istisqa prayer, Mu'awiyah said to Abu Muslim, "Don't you know what this society wants?"

Abu Muslim replied, 'Could I do it while I have many shortcomings.'

Then he rose, on his head he wore a kind of headgear. Then the headgear is opened, then he raises his hands while praying, Allah O Allah, actually it is only for You that we ask for rain. I come to face you with all my sins. Don't refuse my request. 'So before the people left, the rain fell.

Abu Muslim has a degree, ‘O Allah, in fact Mu’awiyah has appointed me to a position full of sum'ah (actions carried out with the intention that others hear / know, pent.). If there is one good for me, then accept me by your side.

That event happened on Thursday. And on the following Thursday Abu Muslim died. "(Az-Zuhd, by Imam Ahmad, p. 392.)
