The Banu Umayah were cursed and hated by the Holy Prophet (s)
We read in Itehaaf al-Mahra, by Busiri, Volume 8 page 81:
وَعَنْ أَبِي بَرْزَةَ- رَضِيَ اللَّهُ عَنْهُ- قَالَ: “كَانَ أَبْغَضَ الْأَحْيَاءِ- أَوِ النَّاسُ- إِلَى رَسُولِ اللَّهِ – صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ -: بَنُو أُمَيَّةَ، وَثَقِيفٌ، وَبَنُو حَنِيفَةَ”.
رَوَاهُ أَبُو يَعْلَى الْمَوْصِلِيُّ وَأَحْمَدُ بْنُ حَنْبَلٍ وَالْحَاكِمُ وَقَالَ: صَحِيحٌ عَلَى شَرْطِ الشَّيْخَيْنِ.
Abu Dhar (ra) said: ‘The people that Allah’s Apostle hated the most were the Banu Umaya, Thaqif and Banu Hanifa’
This has been recorded by Abu Ya’ala al-Moseli, Ahmand ibn Hanbal, and Hakem, and he (Hakim) termed it as Sahih according to the two Sheikhs standards.
Imam Ibn Hajar Asqalani in his book Matalib al-Aliyah captioned a chapter:
بَابُ لَعْنِ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ الْحَكَمَ بْنَ أبي الْعَاصِ وبنيه وبني أمية
Chapter: The Prophet (s) cursed al-Hakam bin Abi al-Aas, his sons and the Bani Umayah.
Dhahabi in Tareekh Islam, Volume 2 page 200 has recorded the following tradition and declared it to be Sahih:
Al-Shaibi said: ‘I heard Ibn al-Zubair saying: ‘I swear by the Lord of this House (Kaaba) that al-Hakam bin Abi Al-Aas and his sons were cursed by the tongue of Muhamad (s)’’
Al-Hakam was Uthman’s uncle. Marwan was his son, and he was a key governor of Muawiya during his reign. Prior to that, both were blue eyed eyes during the caliphate of Uthman who was the poster boy for the Bani Umayah.
Under the chapter Ibn Hajar Asqalani has recorded some Hadiths to that effect. Ibn Hajar Makki al-Haythami has also recorded such reports that confirm that Bani Umayah’s governor Marwan used to curse the Ahlulbayt (as) and the Ahlulbayt (as) brought to his attention the fact that he was already cursed by the Prophet (s).
. “There is another tradition with Thiqa narrators relating to when Marwan became ruler over Madina and proceeded to abuse Ali every Friday from the pulpit. Saeed bin Aas then became Wali (Governor) of Madina, he didn’t say anything but when Marwan returned as Wali he started uttering the same absurdities again. Hadhrat Hasan knew about this and would remain silent and he would enter the mosque at the time of Takbeer only, when Marwan became dissatisfied with the patience of Hasan (ra) he sent him some appalling messages about him and his respected father. His absurdities included this sentence that “Your example is like that of a mule for when it is asked who its father is, it will reply: “a horse”. Hadhrat Hasan said the messenger said: ‘Go back and tell Marwan: ‘By calling names to you, we do not want to remove whatever you have said against us. Verily we shall both appear before Allah. If you are ruled upon as a liar, Allah is the Greatest for taking revenge.” Verily Marwan has indeed ‘respected’ my grandfather Prophet (s) by giving me the similitude of a mule!” When returning the messenger met Hadhrat Hussain and after forcing him, he told him the statement of Marwan. Hadhrat Hussain said: “Tell Marwan: Take information about your father and your people yourself, as the sign between you and me is that the curse of the Holy Prophet (s) has stuck between your two shoulders”

In Siyar Alam an-Nubala, Volume 10 page 402 we read that Bani Umayah used to name their children after the names of Ahlulbayt so that they an curse their children day and night without any issue.
حكى المدائني أنه أدخل على المأمون، فحدثه بأحاديث في علي، فلعن بني أمية، فقلت: حدثني المثنى بن عبد الله الانصاري قال: كنت بالشام، فجعلت لا أسمع عليا، ولا حسنا، إنما أسمع: معاوية، يزيد، الوليد. مررت برجل على بابه: فقال: اسقه يا حسن، فقلت: أسميت حسنا ؟ فقال: أولادي: حسن، وحسين، وجعفر، فإن أهل الشام يسمون أولادهم بأسماء خلفاء الله، ثم يلعن الرجل ولده ويشتمه. قلت: ظننتك خير أهل الشام، وإذا ليس في جهنم شر منك، فقال المأمون: لا جرم قد جعل الله من يلعن أحياءهم وأمواتهم (3) -يريد الناصبة.
“al-Madaini narrated that he entered upon Mamoon and mentioned to him Hadiths about Ali so Mamoon cursed Bani Ummayah. Then I (al-Madaini) said that al-Mathani bin Abdullah al-Ansari said: ‘I was in Sriya and I never heard the names of Ali and Hassan and rather what I heard was Muaiwya, Yazeed and al-Waleed’. Then I went pass a man who was standing at his door who said: ‘Give him water O Hassan’. I said: ‘You have named him Hassan?’.He replied: ‘My children are named as Hassan, Hussain and Jafar because the people of Syria name their children after the names of caliphs of Allah and then the man [father] curses his son’. Thus I said: ‘I thought you were the best amongst the people of Syria but now I realize that there will be nobody worse than you in the Hellfire’. So Mamoon said: ‘Don’t bother, that is why Allah has cursed those that are alive and dead, by this, he meant the Nawasib”.
In Itehaaf al-Mahara, by Busiri, Volume 5 page 233 pointed out the tampering Bani Ummayah would do with the merits of Ali bin Abi Talib and subsitiute them with one of Ummayads.
قَالَ إِسْحَاقُ: وأبنا عبد الرزاق، أبنا مَعْمَرٌ قَالَ: “سَأَلْتُ الزُّهْرِيَّ: مَنْ كَاتِبُ الْكِتَابِ يَوْمَئِذٍ؟ فَضَحِكَ وَقَالَ: هُوَ عَلِيٌّ، وَلَوْ سَأَلْتَ هَؤُلَاءِ- يَعْنِي بَنِي أُمَيَّةَ- لَقَالُوا: هُوَ عُثْمَانُ “.
Ma’amar said: ‘I asked Zuhuri who wrote the covenant on the day (Hudaybya)?’ He laughed and said: ‘It was Ali, but if you asked those –meaning the Banu Ummaya- they would say it was Uthman’.
