http://en.wikipedia.org/wiki/Ja%60far_ibn_Ab%C4%AB_T%C4%81lib#In_the_Battle_of_ Mu.27t I haven't heard the speech yet. No other sahabi's lifestory moves me as much as Sayyidna Bilal's (radiAllahu Ta'ala anhu). I can't help my tears each time I hear about the incident after the wisaal of the Prophet (sallaLLahu alayhi wassallam) when Sayyidna Bilal failed to complete the adhan and fell down unconscious. Another incident which always makes me cry is Jafar Tayyar's brave attempt to hold the standard when his arms were cut off in the battle of Mu'tah.
Brothers, few speeches are as full of ishq e Mustafa صلى الله عليه وسلم as this one. It made even a hard-hearted dog like me cry... Highly recommended. (In a mixture of Punjabi and Urdu). May Allah grant all of us true ishq e Rasool صلى الله عليه وسلم: and make us die on imaan.
