Dont get too emotional. I think you havnt checked the link above. Prophet actually prayed for ibn ubbayi on his death bed. This is what mentioned there with sources.
Same way prophet made supplication for Muawiya in his life. Obviously not after his death.
BUT
ALLAH says:
Ask forgiveness for them, [O Muhammad], or do not ask forgiveness for them. If you should ask forgiveness for them seventy times - never will Allah forgive them. That is because they disbelieved in Allah and His Messenger, and Allah does not guide the defiantly disobedient people. Tauba -80
This applys to everyone including ibn ubbayi and muawiya and all of us. Dua/supplication is not any merit, that's what I am saying. Infact Prophet had supplicated for his entire ummah that they may be guided. Now its upto Allah, to accept in favor of whom He wants. Because only Allah knows what will happen in future, what everyone will do in future, what is inside the heart (intention).
Life of muawiya after the 3rd caliph is itself evidence that dua of Prophet was rejected by Allah in his favor. He was not a guided person. As he commited many sinful acts throughout his 20 years of rule. Its recorded in both hadith and history books.
Dont follow your emotions. Accept the truth.
Tells everyone not to get emotional > is clearly getting emotional and desperate
Firstly your response was constructed poorly with regards to its English so thats literally what you wrote. Which to be honest speaks volumes about your research.
Secondly these are two totally different things. The Prophet is praying for him
on his deathbed, which as any Muslim knows is a totally different scenario to the way the Prophet gave du'a for Mu'awiyah.
When the Prophet gave du'a for Mu'awiyah he prayed that he be successful in this world, not just to ask that he is forgiven for any vices and what not.
Not just this but how many narrations do we have of 'Abdullah ibn Ubayy being rebuked as a munafiq by the Sahabah? Find me a narration where a Sahabi calls Mu'awiyah a munafiq openly. You won't find one.
Thirdly you shamefully forget that the reason Mu'awiyah rose up was because 'Uthman's killers had not been found. If he was interested in power he would've joined with 'Aisha.
Not just this but like I said. If Mu'awiyah was a Munafiq it would've been clear from early on, so why would the Prophet do it in the first place. Also interestingly you forget that the Prophets du'a came true because Mu'awiyah woukd rule Sham then the whole Muslim world and his rule would also be successful.
So the Prophet's du'a was accepted.
