In the year 2000, Mufti Taha Karaan was invited to debate a famous Shīʿī dāʿī, Dr. Hosseni from Iran. The debate covered several pertinent topics, including: the distortion of the Qurʾān; the authority of the Ahl al-Bayt in light of the Qurʾān and Sunnah; the verses of purification; the wives of the Prophet; the people of Badr; and the concept of abrogation (naskh).
