Is it possible for a person to do ‘Umrah at any time of the day or night? Or must the actions of ‘Umrah be done at a specific time of day?

What I mean by my question is:

All the actions of ‘Umrah are obligatory, so is it possible for a person to do tawaaf (circumambulation of the Ka ‘bah) after ‘Isha’ prayer, if he reaches Makkah before ‘Isha’ time?


Praise
be to Allah.

There is no
specific time for circumambulation of the Ka‘bah (tawaaf); rather whenever a
person who wants to perform Hajj or ‘Umrah, or the person who wants to
perform tawaaf, reaches the Ka‘bah, he may perform tawaaf at any time he
wants of the night or day, even if that is during the times when the prayer
is disallowed, because the Prophet (blessings and peace of Allah be upon
him) said: “O Banu ‘Abd Manaaf, do not prevent anyone from circumambulating
this House or praying at any time he wants, night or day.”

best.
