Assalmoelaikoem warahmatullahi wbarakatuh,
Brother Riskyguy why are you using wikipedia? Do you know who wrote this article? Do you thinks they have used the references with proper manner?
Do you understand what he is writing. What does the letter ( l) means after the name Muawya Radiallahu 3anhu?
May Allah protect us.
