Narrated Muhammad bin Abi Bakr Al-Thaqafi: While we were going from Mina to `Arafat, I asked Anas bin Malik, about Talbiya, "How did you use to say Talbiya in the company of the Prophet?" Anas said: "People used to say Talbiya and their saying was not objected to and they used to say Takbir and that was not objected to either. "

حَدَّثَنَا أَبُو نُعَيْمٍ، قَالَ حَدَّثَنَا مَالِكُ بْنُ أَنَسٍ، قَالَ حَدَّثَنِي مُحَمَّدُ بْنُ أَبِي بَكْرٍ الثَّقَفِيُّ، قَالَ سَأَلْتُ أَنَسًا وَنَحْنُ غَادِيَانِ مِنْ مِنًى إِلَى عَرَفَاتٍ عَنِ التَّلْبِيَةِ كَيْفَ كُنْتُمْ تَصْنَعُونَ مَعَ النَّبِيِّ صلى الله عليه وسلم قَالَ كَانَ يُلَبِّي الْمُلَبِّي لاَ يُنْكَرُ عَلَيْهِ، وَيُكَبِّرُ الْمُكَبِّرُ فَلاَ يُنْكَرُ عَلَيْهِ.
