Performing `Umrah repeatedly be a person visiting
Makkah for a short period of time was not the practice of the Prophet (peace be upon him) or his Companions (may Allah be pleased with them). If this practice had been the best, they would have hastened to do it. It is Islamically prescribed for a person visiting
Makkah and having finished their rituals to do much of Tawaf (circumambulation of the Ka`bah), recitation of the Qur'an, Salah (Prayer), Sadaqah (voluntary charity) and other acts of worships. Also, it is permissible for them to perform `Umrah for themselves or for others whom they can perform `Umrah on their behalf such as the dead and those who are not able to do so because of being old-aged or chronically ill as long as this will incur no hardship for them or for other people during the time when it is very crowded. This is because the Prophet (peace be upon him) said:
(The performance of) `Umrah is an expiation for the sins committed (between it and the previous one). And the reward of Hajj Mabrur (the one accepted by Allah) is nothing except Paradise.
It was also authentically reported that the Prophet (peace be upon him) ordered
`Aishah (may Allah be pleased with her) to perform `Umrah from Tan`im after she had finished the state of Ihram for Hajj and `Umrah when she asked his permission to do so.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
