عقبة بن عامر الجهني
Uqba ibn Amir al-Juhani RA was a Companion who preserved two memorable sermons of the Prophet ﷺ: the short, dense khutbah he gave at Tabuk in 9 AH, beginning that the most truthful speech is the Book of Allah, and, in Sahih al-Bukhari, the farewell to the martyrs of Uhud in the Prophet ﷺ's final illness, when he said he feared not that his ummah would fall into shirk, but that they would compete for this world.
