Talbiyah that is labbaik
On arrival at miqaath - On wearing ihram – On performing nafil prayers – On making an Intention

May the intention be for umrah or hajj or for Hajj e qiraan in all these three cases after the intention (niyyath) saying labbaik at least once is necessary and saying three times is better. The labbaik is : لَبَّیْکَ ط اَللّٰھُمَّ لَبَیَّکْ ط لَبَّیْکَ لَا شَرِیْکَ لَکَ لَبَّیْکَ ط اِنَّ الْحَمْدَ وَالنِّعْمَۃَ لَکَ وَالْمُلْکَ لَا شَرِیْکَ لَکَ ط
Translation of talbiyah: Here I am, Oh Allah the glorified! 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.
