It was narrated from 'Abdullah bin 'Umar that the Prophet used to say: "Labbaika Allahumma Labbaik, Labbaika la sharika laka labbaik. Innal-hamda wan-ni'mata laka wal-mulk, la sharika lak (Here I am, O Allah, here I am. Here I am, You have no partner, here I am. Verily all praise and blessings are Yours, and all sovereignty, You have no partner)."

أَخْبَرَنَا أَحْمَدُ بْنُ عَبْدِ اللَّهِ بْنِ الْحَكَمِ، قَالَ حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ، قَالَ حَدَّثَنَا شُعْبَةُ، قَالَ سَمِعْتُ زَيْدًا، وَأَبَا، بَكْرٍ ابْنَىْ مُحَمَّدِ بْنِ زَيْدٍ أَنَّهُمَا سَمِعَا نَافِعًا، يُحَدِّثُ عَنْ عَبْدِ اللَّهِ بْنِ عُمَرَ، عَنِ النَّبِيِّ صلى الله عليه وسلم أَنَّهُ كَانَ يَقُولُ ‏ "‏ لَبَّيْكَ اللَّهُمَّ لَبَّيْكَ لَبَّيْكَ لاَ شَرِيكَ لَكَ لَبَّيْكَ إِنَّ الْحَمْدَ وَالنِّعْمَةَ لَكَ وَالْمُلْكَ لاَ شَرِيكَ لَكَ ‏"‏ ‏.‏
