Fiqh-us-Sunnah - 5.31

Hadith 5.31.1

Ihram is the intention to perform either Hajj or 'Umrah, or to make intention of performing both. Intention is an important element of both. Allah says: "And they have been commanded no more than this: to worship Allah, offering Him sincere devotion.'' (Qur'an 98.5) The Prophet (peace be upon him) said: "The actions will be rewarded according to the intentions behind them, and every person will have what he had intended."
We have dealt with the subject of intention in Fiqh us-Sunnah, Vol.1.(See the chapter on Wudu in Fiqh us-Sunnah vol. 1) The human heart is its seat. Al-Kamal bin al-Homam reported, "We are unaware of anyone among the narrators reporting about the rites performed by the Prophet (peace be upon him) and saying that he (the Prophet) declared his intention to perform Hajj or 'Umrah aloud saying, "I have made the intention to make 'Umrah or Hajj."

Hadith 5.31.C

Cleanliness

This means clipping one's fingernails, trimming the moustache, shaving off the hair from under the armpits, shaving the pubic hair, making an ablution or preferably taking a complete bath, and in the case of men, to comb their beard and hair.
Ibn 'Umar said: "It is sunnah for a pilgrim to take a complete bath before entering the state of ihram or before entering Makkah." This is reported by Al-Bazzar, Ad-Daraqutni, Al-Hakim, who considers it a sound hadith.
It is reported from Ibn 'Abbas that Allah's Messenger (peace be upon him) said: "A woman in the state of confinement after childbirth and one in her menstruation period must take a complete bath, declare her ihram, and perform all the rites except circumambulation around the Ka'bah, which she may perform after she is in a state of purification." (Ahmad, Ahu Daw+ud, and Tirmidhi who considers this hadith sound)
