All praise and thanks are due to Allah, and peace and blessings be upon His Messenger.
In this fatwa:
It is fine to take some rest and recuperate after the tedious journey to ensure that we perform the rituals of `umrah with energy.
Responding to your question, Sheikh Ahmad Kutty, a senior lecturer and an Islamic scholar at the Islamic Institute of Toronto, Ontario, Canada, states:
It is fine to take some rest and recuperate after the tedious journey to ensure that we perform the rituals of `umrah with energy. The Prophet (peace be upon him) told us regarding prayer: “Pray according to the level of your energy.” He also advised us to make dhikr and dua while we are mentally and spiritually awake. So, we can extend the same to performing tawaf and sa`i, for, he himself has told us that such rites are instituted solely for the purpose of celebrating the remembrance of Allah.
Almighty Allah knows best.
