[Machine] When Ibrahim (Abraham) built the house, Allah revealed to him to proclaim the pilgrimage to the people. Ibrahim said, "Behold, Allah has chosen this house as a place of worship and He has commanded you to perform pilgrimage to it." So, in response to his call, everything that could hear, be it stone, tree, or sand, responded, "Labbaik Allahumma Labbaik" (O Allah, here I am, answering Your call)."  

لَمَّا بَنَى إِبْرَاهِيمُ الْبَيْتَ أَوْحَى اللَّهُ إِلَيْهِ أَنْ أَذِّنْ فِي النَّاسِ بِالْحَجِّ قَالَ فَقَالَ إِبْرَاهِيمُ أَلَا إِنَّ رَبَّكُمْ قَدِ اتَّخَذَ بَيْتًا وَأَمَرَكُمْ أَنْ تَحُجُّوهُ فَاسْتَجَابَ لَهُ مَا سَمِعَهُ مِنْ حَجَرٍ أَوْ شَجَرٍ أَوْ أَكَمَةٍ أَوْ تُرَابٍ لَبَّيْكَ اللَّهُمَّ لَبَّيْكَ
