'Abdullah b. 'Umar (Allah be pleased with them) reported that the Messenger of Allah (ﷺ) entered upon the state of Ihram near the mosque at Dhu'l-Hulaifa as his camel stood by it and he said:

Here I am at Your service, O Lord; here I am at Your service: here I am at Your service. There is no associate with You. Here I am at Your service. All praise and grace is due to You and the sovereignty (too). There is no associate with You. They (the people) said that 'Abdullah b. 'Umar said that that was the Talbiya of the Messenger of Allah (ﷺ). Nafi' said: 'Abdullah (Allah be pleased with him) made this addition to it: Here I am at Your service; here I am at Your service; ready to obey You. The Good is in Your Hand. Here I am at Your service. Unto You is the petition and deed (is also for You).

حَدَّثَنَا مُحَمَّدُ بْنُ عَبَّادٍ، حَدَّثَنَا حَاتِمٌ، - يَعْنِي ابْنَ إِسْمَاعِيلَ - عَنْ مُوسَى بْنِ عُقْبَةَ، عَنْ سَالِمِ بْنِ عَبْدِ اللَّهِ بْنِ عُمَرَ، وَنَافِعٍ، مَوْلَى عَبْدِ اللَّهِ وَحَمْزَةَ بْنِ عَبْدِ اللَّهِ عَنْ عَبْدِ اللَّهِ، بْنِ عُمَرَ - رضى الله عنهما - أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم كَانَ إِذَا اسْتَوَتْ بِهِ رَاحِلَتُهُ قَائِمَةً عِنْدَ مَسْجِدِ ذِي الْحُلَيْفَةِ أَهَلَّ فَقَالَ ‏

‏ لَبَّيْكَ اللَّهُمَّ لَبَّيْكَ لَبَّيْكَ لاَ شَرِيكَ لَكَ لَبَّيْكَ إِنَّ الْحَمْدَ وَالنِّعْمَةَ لَكَ وَالْمُلْكَ لاَ شَرِيكَ لَكَ ‏

‏ ‏.‏ قَالُوا وَكَانَ عَبْدُ اللَّهِ بْنُ عُمَرَ - رضى الله عنهما - يَقُولُ هَذِهِ تَلْبِيَةُ رَسُولِ اللَّهِ صلى الله عليه وسلم ‏.‏ قَالَ نَافِعٌ كَانَ عَبْدُ اللَّهِ - رضى الله عنه - يَزِيدُ مَعَ هَذَا لَبَّيْكَ لَبَّيْكَ وَسَعْدَيْكَ وَالْخَيْرُ بِيَدَيْكَ لَبَّيْكَ وَالرَّغْبَاءُ إِلَيْكَ وَالْعَمَلُ ‏.‏
