Is it wrong to tell better stories than someone else?

ishaq 308; half way to medina, osba was called out to be executed. since the other prisoners were being held for ransum. acba ask mohammad why he was being treated more harshly than the other captives. the prophet said because of your enmity to allah and his prophet; and my little girl; cried ocba in bitterness, who will take care of her? hell fire screamed mohammad and at that moment he was beheaded; wretch that you were [mohammad eulogized] you scoffed at me and claimed that your stories were better than mine. i give thanks that allah has slain you and comforted me. this is when allah sent sura 8:68 to mohammad; so how many believe it is wrong to murder someone just because they tell better stories than you. also i thought all non-muslims buried their daughters alive and didn't love them as ocba did.
