Muhammad b. Abu Bakr ath-Thaqafi said that he asked Anas b. Malik when they were going in the morning from Mina to ‘Arafa how they used to conduct themselves on that day along with God’s messenger, and he replied, “Those of us who raised their voices in the talbiya did so without any objection being made, and those of us who cried ‘God is most great’ did so without any objection being made." Bukhari and Muslim.
عَن محمدِ بن أبي بكرٍ الثَقَفيُّ أَنَّهُ سَأَلَ أَنَسَ بْنَ مَالِكٍ وَهُمَا غَادِيَانِ مِنْ مِنًى إِلَى عَرَفَةَ: كَيْفَ كُنْتُمْ تَصْنَعُونَ فِي هَذَا الْيَوْمِ مَعَ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ؟ فَقَالَ: كَانَ يُهِلُّ مِنَّا الْمُهِلُّ فَلَا يُنْكَرُ عَلَيْهِ وَيُكَبِّرُ الْمُكَبِّرُ مِنَّا فَلَا يُنكَرُ عَلَيْهِ
