Is ghusl (full ritual bath) required before entering the state of ihram?

Ghusl before entering ihram is a Sunnah mu'akkadah (emphasized recommended practice) according to the consensus of the four schools of jurisprudence, but it is not an obligation (wajib) or condition (shart) for the validity of ihram. This means that if a pilgrim enters ihram without performing ghusl — whether due to lack of water, time constraints, or any other reason — their ihram is completely valid and no penalty (fidyah or dam) is required. Sheikh Ibn Uthaymeen explicitly stated that performing wudu alone is sufficient if ghusl is not possible.

The Sunnah basis for ghusl before ihram comes from multiple narrations. The Prophet (peace be upon him) performed ghusl before entering ihram at Dhul-Hulayfah, and he instructed Asma bint Umays, who had just given birth, to perform ghusl and then enter ihram, demonstrating that ghusl before ihram is recommended even for women in a state of post-natal bleeding (nifas). Similarly, the Prophet instructed Aisha when she began menstruating to perform ghusl and enter ihram for Hajj, showing that this ghusl is for cleanliness and the Sunnah of ihram, not for ritual purity.

Scholars note that if water is unavailable, tayammum (dry ablution) does not substitute for the ghusl of ihram, because this ghusl is a Sunnah for cleanliness rather than a required act of purification. The pilgrim should simply enter ihram without it. Ibn Baz confirmed that the ihram is valid with or without the ghusl, and the pilgrim loses only the extra reward of following this particular Sunnah.
