Sahih al-Bukhari
Holding Fast to the Qur'an and Sunnah
Chapter: “A group of my followers will remain victorious in their struggle in the cause of the Truth.”
Narrated Humaid:
I heard Muawiya bin Abi Sufyan delivering a sermon. He said, "I heard the Prophet (ﷺ) 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."
