The Prophet (peace and blessings be upon him) said, “Islam is built upon five pillars: testifying that there is no true god except Allah and that Muhammad is the Messenger of Allah, performing Prayer, paying the Zakah, making the pilgrimage to the Sacred House (Hajj), and fasting the month of Ramadan.” (Reported by Al-Bukhari) Also, we’d would like to commend your pursuit of Islamic counseling.
Dr. Rif`at Fawzi, former professor of Shari`ah at Cairo Univ. , states: “There is nothing wrong as far as Islamic Shari`ah is concerned in using unperfumed soap for washing hands, taking a shower, etc. during ihram. Also, light fragrance can be tolerated in soap especially if you cannot find unperfumed soap. May Allah reward you and grant you Hajj Mabrur (the one accepted by Allah).”
Allah Almighty knows best.
