Quraish didn't think they were associating partners with God

وَحَدَّثَنِي عَبَّاسُ بْنُ عَبْدِ الْعَظِيمِ الْعَنْبَرِيُّ، حَدَّثَنَا النَّضْرُ بْنُ مُحَمَّدٍ الْيَمَامِيُّ، حَدَّثَنَا عِكْرِمَةُ، - يَعْنِي ابْنَ عَمَّارٍ - حَدَّثَنَا أَبُو زُمَيْلٍ، عَنِ ابْنِ عَبَّاسٍ، - رضى الله عنهما - قَالَ كَانَ الْمُشْرِكُونَ يَقُولُونَ لَبَّيْكَ لاَ شَرِيكَ لَكَ - قَالَ - فَيَقُولُ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏ "‏ وَيْلَكُمْ قَدْ قَدْ ‏"‏ ‏.‏ فَيَقُولُونَ إِلاَّ شَرِيكًا هُوَ لَكَ تَمْلِكُهُ وَمَا مَلَكَ ‏.‏ يَقُولُونَ هَذَا وَهُمْ يَطُوفُونَ بِالْبَيْتِ ‏.‏

Ibn 'Abbas (Allah be pleased with them) reported that the polytheists also pronounced (Talbiya) as: Here I am at Thy service, there is no associate with Thee. The Messenger of Allah (ﷺ) said: Woe be upon them, as they also said: But one associate with Thee, you possess mastery over him, but he does not possess mastery (over you). They used to say this and circumambulate the Ka'ba.
