Nonetheless, the Almohads, particularly from the reign of Caliph Abu Yusuf Ya'qub al-Mansur onward, embraced the use of logical reasoning as a method of validating the more central Almohad concept of tawhid. This effectively provided a religious justification for philosophy and for a rationalist intellectualism in Almohad religious thought. Al-Mansur's father, Abu Ya'qub Yusuf, had also shown some favour towards philosophy and kept the philosopher Ibn Tufayl as his confidant. Ibn Tufayl in turn introduced Ibn Rush (Averroes) to the Almohad court, to whom Al-Mansur gave patronage and protection. Although Ibn Rushd (who was also an Islamic judge) saw rationalism and philosophy as complimentary to religion and revelation, his views failed to convince the traditional Maliki ulema, with whom the Almohads were already at odds. After the decline of Almohadism, Maliki Sunnism ultimately became the dominant official religious doctrine of the region. By contrast, the teachings of Ibn Rushd and other philosophers like him were far more influential for Jewish philosophers – including Maimonides, his contemporary – and Christian Latin scholars – like Thomas Aquinas – who later promoted his commentaries on Aristotle.
