What is the ruling on a man wearing the Ihram garments? Is it one of the pillars of Umrah, one of its obligations, or one of its Sunnahs? And why did scholars not consider it one of the obligations? Did scholars differ regarding considering exiting Ihram (tahallul) one of the obligations of Umrah? And why was it not considered one of its pillars, even though Umrah is not complete without it? And what is the difference between intentionally or unintentionally or forgetfully omitting a pillar or an obligation of Umrah?

To clarify some matters related to Ihram:

1. Removing tailored or sewn garments (التجرد من المخيط أو المحيط): This is one of the obligations of Ihram, meaning not wearing anything that is tailored to the body, as stated in the noble prophetic Hadith: "He should not wear a shirt, nor trousers, nor a burnous..."

2. Ihram in the Izar and Rida' (الإحرام في الإزار والرداء): This is recommendable, not obligatory. The statement in the Hadith, "And let one of you enter into Ihram in an izar, a rida', and two sandals," is for recommendation, not obligation. Thus, it is permissible to wrap any cloth around the body, and wearing sandals is not obligatory.

3. Shaving and shortening the hair (الحلق والتقصير): Scholars differed on whether these are among the obligations of Umrah.

4. The difference between abandoning pillars and abandoning obligations: Abandoning an obligation: Necessitates a dam (expiation/sacrifice). Abandoning a pillar: The Umrah or Hajj is not complete except by performing it, and the ritual is not valid without it, whether the abandonment was intentional, due to ignorance, or forgetfulness. The pillars of Umrah are: Ihram, Tawaf, and Sa'y.
