((لَبَّيْكَ اللَّهُمَّ لَبَّيْكَ، لَبَّيْكَ لاَ شَرِيكَ لَكَ لَبَّيْكَ، إِنَّ الْحَمْدَ، وَالنِّعْمَةَ، لَكَ وَالْمُلْكَ، لاَ شَرِيكَ لَكَ)).
(Here I am O Allah, (in response to Your call), here I am. Here I am, You have no partner, here I am. Verily all praise, grace and sovereignty belong to You. You have no partner.)
