Logic in Islamic law and theology Early forms of analogical reasoning, inductive reasoning and categorical syllogism were introduced in Fiqh (Islamic jurisprudence), Sharia and Kalam (Islamic theology) from the 7th century with the process of Qiyas, before the Arabic translations of Aristotle's works. Later, during the Islamic Golden Age, there was debate among Islamic philosophers, logicians and theologians over whether the term Qiyas refers to analogical reasoning, inductive reasoning or categorical syllogism. Some Islamic scholars argued that Qiyas refers to inductive reasoning. Ibn Hazm (994–1064) disagreed, arguing that Qiyas does not refer to inductive reasoning but to categorical syllogistic reasoning in a real sense and analogical reasoning in a metaphorical sense. On the other hand, al-Ghazali (1058–1111; and, in modern times, Abu Muhammad Asem al-Maqdisi) argued that Qiyas refers to analogical reasoning in a real sense and categorical syllogism in a metaphorical sense. Other Islamic scholars at the time, however, argued that the term Qiyas refers to both analogical reasoning and categorical syllogism in a real sense.Wael B.
