[Machine] About the phrase that the Messenger of Allah ﷺ used to recite while entering Makkah, he would say, "Labbaik Allahumma labbaik, labbaik la sharika laka labbaik. Innal hamda wanni'mata laka wal mulk, la sharika lak." [Narrated by Al-Nasa'i].
It was mentioned by beneficial narrations that Ibn 'Umar used to increase these words when performing tawaf, saying, "Labbaik wa-al-rujba'a ilayka wal-'amal labbaik labbaik."
عَنِ الَّذِي كَانَ رَسُولُ اللهِ ﷺ يُلَبِّي بِهِ يَقُولُ لَبَّيْكَ اللهُمَّ لَبَّيْكَ لَبَّيْكَ لَا شَرِيكَ لَكَ لَبَّيْكَ إِنَّ الْحَمْدَ وَالنِّعْمَةَ لَكَ وَالْمُلْكَ لَا شَرِيكَ لَكَ وَذَكَرَ نَافِعٌ أَنَّ ابْنَعُمَرَ كَانَ يَزِيدُ هَؤُلَاءِ الْكَلِمَاتِ مِنْ عِنْدِهِ لَبَّيْكَ وَالرَّغْبَاءُ إِلَيْكَ وَالْعَمَلُ لَبَّيْكَ لَبَّيْكَ
