There is no harm in that, because the Prophet (ﷺ) heard those who were
saying the Talbiya differently than him and did not object.
Nafi’ said: Ibn Omar was increasing his Talbiya by saying: “Labbayka was-sa’daik wal-khairu bayna yadayk, Labbayka was-raghba’u ilayka wal-amal” which translates to “Here I am, and at Your
service; all good is in Your hands, here I am, I respond to Your call and the requests
and deeds are for You.”
