"I was with Ibn Abbas in Arafat and he said: 'Why do I not hear the people reciting Talbiyah?' I said: They are afraid of Muawiyah.' So Ibn Abbas went out of his tent and said: "Labbaik Allahumma Labbaik, Labbaik! They are only forsaking the Sunnah out of hatred for Ali.'" (Using translation from Nasāʾī 3006)  

«لَبَّيْكَ اللهُمَّ لَبَّيْكَ لَبَّيْكَ فَإِنَّهُمْ قَدْ تَرَكُوا السُّنَّةَ مِنْ بُغْضِ عَلِيٍّ»
