Is it prescribed to add to the talbiyah narrated by Jabir?

The Shaykh : Now, this is the talbiyah of the Messenger (peace and blessings be upon him), as Jabir stated. Are we permitted to add to it? We say that Ahmad narrated in al-Musnad that the Prophet (peace and blessings be upon him) used to say and "this is the true God," which is an addition of the described to His attribute, meaning "Here I am, You are the true God." And Ibn Umar used to add "Here I am, and here I am to obey you, and the good is in Your hands, and the desire is toward You, and the deed". So if a person adds words like these, we hope there is no harm in it, following the example of whom? Of Abdullah ibn Umar. But it is better to stick to what is established from the Prophet (peace and blessings be upon him). Now, are people permitted to say takbir instead of the talbiyah if it is during the time of takbir in the ten days of Dhul-Hijjah? The answer is yes, based on the statement of Anas (may Allah be pleased with him) "We performed Hajj with the Prophet (peace and blessings be upon him), and some of us were saying takbir and some of us were saying the talbiyah". This indicates that they were not saying the talbiyah collectively; if they had been saying the talbiyah collectively, they would all have been saying the talbiyah, but some were saying takbir and some were saying the talbiyah, and everyone was remembering Allah according to their own state. The scholars said "It is recommended to mention one's type of pilgrimage in the talbiyah, but sometimes" if one is performing 'Umrah, one says "Here I am, O Allah, for 'Umrah," and if for Hajj, "Here I am, O Allah, for Hajj," and if for Qiran, "Here I am, O Allah, for 'Umrah and Hajj."
