Mishkat al-Masabih 10 The Rites of Pilgrimage كتاب المناسك 35

وَعَنِ ابْنِ عُمَرَ رَضِيَ اللَّهُ عَنْهُمَا قَالَ: سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يُهِلُّ مُلَبِّدًا يَقُولُ: «لَبَّيْكَ اللَّهُمَّ لَبَّيْكَ لَبَّيْكَ لَا شَرِيكَ لَكَ لَبَّيْكَ إِنَّ الْحَمْدَ وَالنِّعْمَةَ لَكَ وَالْمُلْكَ لَا شَرِيكَ لَكَ» . لَا يَزِيدُ عَلَى هَؤُلَاءِ الْكَلِمَاتِ

Ibn ‘Umar said that he heard God’s messenger say when with his hair matted he raised his voice in the talbiya , “ Labbaik , O God, labbaik labbaik ; Thou hast no partner; labbaik ; praise and grace are Thine, and the dominion; Thou hast no partner,” saying nothing more than these words. Bukhari and Muslim.
