question #3 Sahih Muslim 1184a, Book 15, Hadith 21 : What are the additional phrases added by ‘Abdullah b. ‘Umar to the Talbiya, and what do they signify?

Here I am at Thy service. O Allah, here I am at Thy service, here I am at Thy service. There is no associate with Thee; here I am at Thy service. Verily all praise and grace is due to Thee, and the sovereignty (too). There is no associate with Thee. He (the narrator) further said that ‘Abdullah b. ‘Umar (Allah be pleased with them) made this addition to it: Here I am at Thy service; here I am at Thy service; ready to obey Thee, and good is in Thy Hand; here I am at Thy service; unto Thee is the petition, and deed (is also for Thee).
