In a sign of his growing support, Ibn ʿAbd al-Wahhāb began to take action in his campaign against shirk by destroying certain objects of veneration. On one occasion, he set out with Ibn Muʿammar and a group of men to destroy the domes and mosques built above the graves of certain of the Prophet’s Companions in al-Jubayla, an area near Riyadh. One of these was the tomb of Zayd ibn al-Khaṭṭāb, the brother of the second caliph, ʿUmar ibn al-Khaṭṭāb.
