Hadith against Mu'awiyah raa

[al-kulayni]

Assalamu Aleykum,

I want to know if this hadith is sahih :

وحدثني إسحاق وبكر بن الهيثم قالا حدثنا عبد الرزاق بن همام انبأنا معمر عن ابن طاوس عن أبيه عن عبد الله بن عمرو بن العاص قال: كنت عند النبي صلى الله عليه وسلم فقال: يطلع عليكم من هذا الفج رجل يموت على غير ملتي، قال: وكنت تركت أبي قد وضع له وضوء، فكنت كحابس البول مخافة أن يجيء، قال: فطلع معاوية فقال النبي صلى الله عليه وسلم : هو هذا

From ansab al ashraf by al baladhuri

In this text, we can see the Prophet (saws) saying to abdallah ibn amr ibn al 'as that one man will come from behind a mount and this man will leave religion, then this man came and it was Mu'awiyah raa.

Some raawafidh say that abdallah al ghumari (the morocan rafidhi) authenticates this hadith.

[Farid]

These guys need to prove the reliability of Al Balathuri before looking at the narrators.

[al-kulayni]

Could you give more détails about al baladhuri ? bfk akhi

[Hani]

Anyone called Ghumari's opinions are rejected when it comes to ANYTHING that is related to Ahlul-Bayt. They're a family of blind extremist when it comes to this.

Secondly, Baladhuri as Farid said, is not a reliable historian who worked for the `Abbasi Caliph.

Thirdly, if your friends had intellect, they'd realize that this text cannot be true, as it makes no sense, if people knew Mu`awiyah is a Kafir no one would have treated him the way they did starting from `Umar and ending with al-Hasan.
