Here I am, O God, at Thy Command!
Here I am at Thy Command! Thou art without associate; Here I am at Thy Command!
Thine are praise and grace and dominion! Thou art without associate.
To neglect chanting Talbiyah or uttering it in a low voice contradicts the Prophetic Sunnah, because the Prophet SAW clarified that men are to chant Talbiyah in a loud voice, while women have to utter it in a low voice.
It is a common mistake not to contemplate the meaning of the words of Talbiyah. These words denote complete submission to Allah and compliance with His orders, turning unto Him with both hope and fear. So, man is to contemplate on the words of Talbiyah in order to pronounce them with full sincerity and awareness of their meaning from the bottom of one’s heart.
Some people consider it necessary to take a guide who pronounces the words of Talbiyah loudly and they are to repeat after him. This, in fact, was not reported in the Prophetic Sunnah, and there is no evidence on it. It also contradicts the authentic acting of the Prophet’s Companions (may Allah be pleased with them all).
