Enemy of the sunnah
Al-Isti’ab fi Ma’rifat al-Ashab pg 747:
وفيه يقولُ أبو الطُّفَيلِ عامرُ بنُ واثِلةَ:
يا هاشمَ الخيرِ جُزِيتَ الجَنَّة
قاتَلتَ في اللَّهِ عَدُوَّ السُّنَّهْ
أفْلِحْ بما فُزْتَ به مِن مِنَّه
In it, Abu al-Tufayl Amir ibn Wathilah says:
O Hashim of goodness, may you be rewarded with Paradise You fought in the cause of Allah against the enemy of the Sunnah. Rejoice in what you have attained of divine grace
