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

Ghusl before entering ihram is a Sunnah mu'akkadah (emphasized sunnet 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 haci enters ihram without performing gusul — 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 abdest alone is sufficient if gusul is not possible.

The Sunnah basis for gusul before ihram comes from multiple narrations. Hz. Peygamber (sallallahu aleyhi ve sellem) performed gusul before entering ihram at Dhul-Hulayfah, and he instructed Asma bint Umays, who had just given birth, to perform gusul and then enter ihram, demonstrating that gusul before ihram is sunnet even for women in a state of post-natal bleeding (nifas). Similarly, Hz. Peygamber instructed Aisha when she began menstruating to perform gusul and enter ihram for Hac, showing that this gusul 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 gusul of ihram, because this gusul is a Sunnah for cleanliness rather than a required act of purification. The haci should simply enter ihram without it. Ibn Baz confirmed that the ihram is valid with or without the gusul, and the haci loses only the extra reward of following this particular Sunnah.
