Abide by religious restrictions while performing Hajj and Umrah pilgrimages.

This hadith explains that it is not permissible for someone who is in the state of ihram to get married or arrange a marriage for themselves or others. The narrator of this hadith is Yahya from Malik from Nafi from Abdullah ibn Umar. The state of ihram refers to the sacred state that Muslims enter when they are performing Hajj and Umrah pilgrimages. During this time, certain activities are prohibited such as getting married or arranging marriages. This hadith serves as an important reminder that those who are in the state of ihram must adhere to these restrictions and refrain from engaging in any activities which would be considered impermissible during this time.
