Musnad Ahmad 2392
Musnad of 'Abdullah bin al-'Abbas bin 'Abdul-Muttalib from the Prophet
It was narrated that ad-Dahhak bin Muzahim said: When Ibn 'Abbas (رضي الله عنه) said the Talbiyah, he would say: “Here I am, O Allah, here I am. Here I am, You have no partner, here I am. Verily all praise and blessings are Yours, and all sovereignty, You have no partner." And Ibn ‘Abbas said: Do it this way, for this is the Talbiyah of the Messenger of Allah (ﷺ)
