Muwatta Malik, Book 20, Hadith 736 (In-Book) ⓘ

Yahya related to me from Malik from Abdullah ibn Umar that the talbiya of the Messenger of Allah, may Allah bless him and grant him peace, was, "I am at Your service, O Allah, I am at Your service. You have no partner. I am at Your service. Praise and blessing belong to You, and the Kingdom. You have no partner." Labayk, Allahumma labayk, la sharika laka labayk. Inna'l-hamda wa'n-nimata laka wa'l-mulk, la sharika lak. Malik said that Abdullah ibn Umar used to add, "I am at Your service, I am at Your service. I am at Your service and at Your call. Good is in Your hands, and I am at Your service. Our desire is for You, and our action." Labayk, labayk, labayk wa sadayka wa'l-khayr biyadayka labayk wa'r-raghba'u ilayka wa'l-amalu.

حَدَّثَنِي يَحْيَى، عَنْ مَالِكٍ، عَنْ نَافِعٍ، عَنْ عَبْدِ اللَّهِ بْنِ عُمَرَ، أَنَّ تَلْبِيَةَ، رَسُولِ اللَّهِ صلى الله عليه وسلم ‏ "‏ لَبَّيْكَ اللَّهُمَّ لَبَّيْكَ لَبَّيْكَ لاَ شَرِيكَ لَكَ لَبَّيْكَ إِنَّ الْحَمْدَ وَالنِّعْمَةَ لَكَ وَالْمُلْكَ لاَ شَرِيكَ لَكَ ‏" ‏ ‏.‏ قَالَ وَكَانَ عَبْدُ اللَّهِ بْنُ عُمَرَ يَزِيدُ فِيهَا لَبَّيْكَ لَبَّيْكَ لَبَّيْكَ وَسَعْدَيْكَ وَالْخَيْرُ بِيَدَيْكَ لَبَّيْكَ وَالرَّغْبَاءُ إِلَيْكَ وَالْعَمَلُ ‏.‏
