Labbayka Allahumma labbayk means: 1- I submit and submit again, 2- I am persisting in obeying You, 3- I confirm my love of Allah, 4- It implies sincerity, 5- It implies drawing close to Allah. 6. It is a symbol of tawhid.

If a person is performing tawaf or sa`i and he comes across a need (e.g., he is thirsty and wants to drink something, or loses someone and stops to look for him, or becomes tired and wants to take some rest), and if the break was short, then he may continue his tawaf from where he left off.
