- Among the Faza'el of Muawiyah (ra):
1- Imam Bukhari narrates: حدَّثنا الحسنُ بن بِشرٍ حدَّثَنا المُعافى عن عثمانَ بنِ الأسودِ عنِ ابن ملَيكةَ قال: «أَوتَرَ مُعاويةُ بعدَ العِشاءِ برَكعةٍ وعندَهُ مَولًى لابنِ عبّاسٍ، فأتى ابنَ عباس، فقال: دَعهُ فإنهُ قد صحِبَ رسولَ اللَّهِ صلى الله عليه وسلّم».
Which means: Muawiyah made a Witr Salat with one Rak'ah with the presence of one servant of Ibn Abbas, so he came to Ibn Abbas (complaining). Ibn Abbas said: leave him for he accompanied Rasoolullah sallallahu alayhi wa sallam.
2- In another narration in Bukhari: حدَّثنا ابنُ أبي مريمَ حدَّثنا نافعُ بن عمرَ حدَّثني ابن أبي مُلَيكةَ «قِيْلَ
لابن عبّاسٍ: هل لكَ في أميرِ المؤمنينَ معاويةَ فإنه ما أَوترَ إلاّ بواحدة، قال: «إنه فقيه».
Ibn Abbas was told: what do you say about amirul muminin Muawiyah for he did Witr only with one rak'ah? Ibn Abbas said: He is a Faqih.
3- Al Khallal narrated with AUTHENTIC isnaad to Ibn Umar (ra): أخبرني محمد بن مخلد ، قال: حدثني أبو منصور بن داود بن طوق الصغاني ، قال: ثنا سعيد بن منصور ، قال: ثنا هشيم ، عن العوام بن حوشب ، عن جبلة بن سحيم ، قال: سمعت ابن عمر ، يقول: « ما رأيت بعد رسول الله صلى الله عليه وسلم أسود من معاوية، فقيل: ولا أبوك؟ قال: أبي عمر رحمه الله خير من معاوية، وكان معاوية أسود منه» .
I heard Ibn Umar saying: " I have never seen anyone after Rasoolullah sallallahu alayhi wa sallam more generous than Muawiyah. He was asked: not evern your father (i.e Sayyidina Umar)?. He replied: My father Umar is better than Muawiyah, but Muawiyah is more generous than him".
4- Saheeh Bukhari Sharif, under the chapter: Bab Thikr Muawiyah Radiya Allahu anhu: حدَّثنا عمرُو بن عبّاسٍ حدثَنا محمدُ بن جعفرٍ حدَّثَنا شعبةُ عن أبي التَّيّاح قال: سمعتُ حُمرانَ بن أبانَ عن معاويةَ رضيَ اللَّهُ عنه قال: «إنكم لَتُصَلُّونَ صلاةً لقد صَحِبْنا النبيَّ صلى الله عليه وسلّم فما رأيناهُ يُصلِّيها، ولقد نهى عنهما، يعني الرَّكعتَينِ بعدَ العصر».
Humran said: Muawiyah radiya Allahu anhu said: You people praying a salat. We have accompanied the Prophet sallallahu alayhi wa sallam and we did not see him pray it, and he prohibit it from praying them, meaning the two Rak'ahs after Asr Salat".
Which shows he accompanied the Prophet, sallallahu alayhi wa aalihi wa sallam, and was knowledgable in the Sunnah.
5- Tha-Habi said in his Siyar 3/133: وقال خليفة : ثم جمع عمر الشام كلها لمعاوية ، وأقره عثمان . قلت : حسبك بمن يُؤمِّره عمر ، ثم عثمان على إقليم – وهو ثغر – فيضبطه ، ويقوم به أتم قيام ، ويرضى الناس بسخائه وحلمه ... فهذا الرجل ساد وساس العالم بكمال عقله ، وفرط حلمه وسعة نفسه وقوة دهائه ورأيه ... ، وكان محببا إلى رعيته ، عمل نيابة الشام عشرين سنة ، والخلافة عشرين سنة ، ولم يهجه أحد في دولته ، بل دانت له الأمم وحكم على العرب والعجم ، وكان ملكه على الحرمين ومصر والشام والعراق ، وخراسان وفارس والجزيرة واليمن والمغرب وغير ذلك "
Which means: " Umar (ra) place the whole lands of Shaam under Muawiyah, and Uthman continued that policy. I said (Tha-Habi ): It is enough (honour) for someone that Umar places him in charge, then Uthman, on an important land, and he controls it well, and takes good care of it, and pleases people with his patience and generosity. This man (Muawiyah) led and controlled the whole world with his perfect mind, excessive patience, big heart, and his strong tactics and smartness. he was beloved to his subjects (Shaami's). He worked as an Amir of Shaam for 20 years, then as a Khalifah for another 20 years, and no one under his rule criticized him, but indeed the nations were under his control and he subjigated the Arabs and non Arabs, and his rulership extended over the Haramayn, Egypt, Shaam, iraq, Khurasan, Persia, Arab peninsula, yaman, and the western hemishere (from the arabian peninsula) and more"
6- From Tarikhul Islam by Tha-Habi with an authentic Isnaad: فعن أبي مسلم الخولاني :" أنه دخل على معاوية فقال له : أنت تنازع علياً أأنت مثله ؟ فقال معاوية : لا والله إني لأعلم أن علياً أفضل وأحق ولكن ألستم تعلمون أن عثمان قتل مظلوماً ؟ وأنا ابن عمه وأنا أطلب بدمه فأتوا علياً فقولوا له فليدفع إليّ قتلة عثمان وأُسلِّم له الأمور ، فَأَتوا عليا فكلموه فأبى عليهم ولم يدفع القتلة ".
Which means: " Abu Muslim Khawlani came to Muawiyah saying: You are fighting with Ali, are you like him?. Muawiyah said: no by Allah I know that Ali is better and more worthy, but don't you know that Uthman was killed unjustly? and I am his cousin and I want the punishment for his blood, so go to Ali and tell him to hand me over the killers of Uthman and I will hand him over the control (of the lands and people). They came to Ali and told him, and he refused and did not hand over the killers".
This narration clears Muawiyah (ra) from the evil things, the Rafidhi's accuse him with. It shows you what Muawiyah's opinoin was based on and what were his views as he presented them to people.
P.S. though this narration is authentic according to Tha-habi, make sure to understand that Ali wanted to have the justice system established in an Islamic court of law, not simply to hand over a group of people who are accused of a crime without verification beyond a doubt to their opponent. Besides, Ali (as) was not involved, nor was he present at the murder of Sayyidina Uthman (ra). Such a big crime requires thorough investigation and verification, that was the stand of Sayyidina Ali. Also, Sayyidina Ali wasnted Muawiyah to follow the Islamic proceedures of taking people to court.i.e. complain against specific people, and give them the chance to asnwer their accusation.
7- Among his Faza'el (ra) that he wrote letters to the Prophet, sallallahu alayhi wa aalihi wa sallam. Some Rafidhi's brought a confusion about this point, and pointed out that Muawiyah (ra) did not write any Ayah of the Qur'an, and therefore he is from Kuttabul-Wahi. Well, it is true that there is no evidence that Muwiyah wrote the Qur'an for teh Prophet, sallallahu alayhi wa aalihi wa sallam, as it was being revealed, BUT he did write letters of correspondence to the Prophet sallallahu alayhi wa aalihi wa sallam, without anyone disagreeing on that. Therefore by definition he is a writer of Wahi, anyway. because what the Prophet, sallallahu alayhi wa aalihi wa sallam, says is also Wahi. So he is a writer of Wahi. be careful to that point.
8- In his time, Cyprus was conquered, and all the Muslims in Cyprus know Islam through Muawiyah (ra)'s army and people. The same applies for the liberation of Constantinople.
