Book 24: The Book of Hajj
It was narrated that Saeed bin Jubair said:
“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.'”
أَخْبَرَنَا أَحْمَدُ بْنُ عُثْمَانَ بْنِ حَكِيمٍ الأَوْدِيُّ، قَالَ حَدَّثَنَا خَالِدُ بْنُ مَخْلَدٍ، قَالَ حَدَّثَنَا عَلِيُّ بْنُ صَالِحٍ، عَنْ مَيْسَرَةَ بْنِ حَبِيبٍ، عَنِ الْمِنْهَالِ بْنِ عَمْرٍو، عَنْ سَعِيدِ بْنِ جُبَيْرٍ، قَالَ كُنْتُ مَعَ ابْنِ عَبَّاسٍ بِعَرَفَاتٍ فَقَالَ مَا لِي لاَ أَسْمَعُ النَّاسَ يُلَبُّونَ قُلْتُ يَخَافُونَ مِنْ مُعَاوِيَةَ . فَخَرَجَ ابْنُ عَبَّاسٍ مِنْ فُسْطَاطِهِ فَقَالَ لَبَّيْكَ اللَّهُمَّ لَبَّيْكَ لَبَّيْكَ فَإِنَّهُمْ قَدْ تَرَكُوا السُّنَّةَ مِنْ بُغْضِ عَلِيٍّ .
