Abdullah ibn Umar reported: The Messenger of Allah, peace and blessings be upon him, would answer the call of the pilgrimage, saying, “At your service, O Allah, at your service. At your service, you have no partner, at your service. Verily, all praise and blessings are for you, the dominion belongs to you, and you have no partner.”
Ibn Umar, may Allah be pleased with him, would add in it, “At your service, at your service, ready to obey you. All good is in your hand, at your service. All hope and deeds are for you.”

عَنْ عَبْدِ اللَّهِ بْنِ عُمَرَ رَضِيَ اللَّهُ عَنْهُمَا أَنَّ تَلْبِيَةَ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ لَبَّيْكَ اللَّهُمَّ لَبَّيْكَ لَبَّيْكَ لَا شَرِيكَ لَكَ لَبَّيْكَ إِنَّ الْحَمْدَ وَالنِّعْمَةَ لَكَ وَالْمُلْكَ لَا شَرِيكَ لَكَ
كَانَ عَبْدُ اللَّهِ بْنُ عُمَرَ رَضِيَ اللَّهُ عَنْهُمَا يَزِيدُ فِيهَا لَبَّيْكَ لَبَّيْكَ وَسَعْدَيْكَ وَالْخَيْرُ بِيَدَيْكَ لَبَّيْكَ وَالرَّغْبَاءُ إِلَيْكَ وَالْعَمَلُ
