What did Prophet Muhammad (saw) say about how long the state of the nation will remain good?
 Narrated Humaid:                     I heard Muawiya bin Abi Sufyan delivering a sermon. He said, "I heard the Prophet saying, "If Allah wants to do a favor to somebody, He bestows on him, the gift of understanding the Qur'an and Sunna. I am but a distributor, and Allah is the Giver. The state of this nation will remain good till the Hour is established, or till Allah's Order comes."
