I would like to know the description of Umrah in detail.

Worship is accepted upon fulfilling two conditions: sincerity to Allah and following the Prophet, peace be upon him. Umrah (definition) consists of four pillars: Ihram (definition), Tawaf (definition), Sa'i, and shaving or shortening the hair.

Description of Umrah: 1. Ihram: The intention to enter into the ritual. It is sunnah (definition) to perform ghusl (definition), perfume oneself, and wear the Ihram garments. Then, one performs two rak'ahs of prayer if it is not an obligatory prayer, then enters into Ihram saying: "Labbayka Allahumma bi Umrah" (Here I am, O Allah, for Umrah), and recites the talbiyah (definition) of the Prophet, peace be upon him. It is recommended for a man to raise his voice with the talbiyah and for a woman to lower it in the presence of non-mahrams. It is legislated to make a condition (ishtirat) if one fears an impediment. The talbiyah continues until the start of Tawaf. 2. Tawaf: Upon entering the Grand Mosque, a man should put his right foot forward and remember Allah. Tawaf begins from the Black Stone; one touches and kisses it if possible, otherwise, one points to it and says "Allahu Akbar." One keeps the Kaaba to their left and says between the Yemeni Corner and the Black Stone: "Rabbana atina fi ad-dunya hasanah wa fi al-akhirati hasanah wa qina adhab an-nar" (Our Lord, give us good in this world and good in the Hereafter, and protect us from the torment of the Fire). It is legislated for a man to uncover his right shoulder (idtiba') and to jog (ramal) in the first three circuits. After seven circuits, one prays two rak'ahs behind Maqam Ibrahim. 3. Sa'i: It begins from Safa. One recites: (Indeed, Safa and Marwa are among the symbols of Allah). One ascends Safa facing the Kaaba, remembers Allah, and supplicates. A man should jog between the two green markers and walk in the rest of the distance. This is repeated until seven circuits are completed, going and returning. 4. Shaving or Shortening the Hair: After Sa'i, a man shaves his head completely or shortens it, and shaving is preferable. A woman shortens her hair by the length of a fingertip.

Upon completing these actions, the Umrah is concluded.
