Tomb of Hud (عليه السلام)
This tomb, in Hadhramaut, Yemen belongs to Hud (عليه السلام) who was sent as a Prophet to the people of ‘Aad. The people of ‘Aad were known uniquely for their mighty strength and size. The majority however, rejected the invitation of Hud (عليه السلام) and were destroyed by a powerful wind. The eleventh Surah of the Holy Quran is named after Hud (عليه السلام).
