It is not permissible for the one who has entered ihram for Hajj or ‘Umrah to exit ihram or stop doing Hajj or ‘Umrah before completing it. If your father is able to go back to Makkah and complete the ‘Umrah, then it is obligatory for him to do that, and he cannot exit that ihram except by completing it, so long as he is able to do that.

Some of the mistake made in tawaf include: 1- Uttering the intention out loud; 2- Pushing and shoving too much when touching Black Stone; 3- Thinking touching the Black Stone is done for barakah; 4- Reciting a specific du’a in each circuit.
