Entering Makkah without assuming Ihram

Q: Two brothers traveled to Makkah Al-Mukarramah during the days of Tashriq (11th, 12th and 13th of Dhul-Hijjah). They neither entered the House (Ka`bah) nor performed Tawaf (circumambulating the Ka`bah) or Sa`y (going between Safa and Marwah) as they were only aiming to receive the body of their dead father while they were in sorrow and absent minded. Moreover, they had never been to Makkah before. What Kaffarah (expiation) they are liable to? May Allah reward you with the best and make our deeds and yours devoted to the sake of Allah, the Ever-Generous.

A: If what you have mentioned is the case, they are not sinful nor liable for any Kaffarah.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
