Hadith 1823
Sayyiduna Abu Umamah (may Allah be pleased with him) said: The Messenger of Allah (peace and blessings be upon him) said: "Whoever is not prevented from performing Hajj by an apparent need, a tyrannical ruler, or a restraining illness, and dies without having performed Hajj, then let him die if he wishes as a Jew or if he wishes as a Christian."
