a fourth source of law was accepted by the majority of later and modern Muslim jurists, this was not the case at the inception of Muslim jurisprudence as a field. Opposition to qiyas came from a number of angles. Professor Walîd b. Ibrâhîm al-`Ujajî Imam Muhammad ibn Saud Islamic University explains the opposition to qiyas as coming from multiple angles: Some of them argued that qiyâs is contrary to reason. One argument given in this light was that: “Delving into this method is intellectually repugnant in its own right”. Another argument was: “Islamic legal rulings are based on human well-being, and no one knows human well-being except the One who gave us the sacred law. Therefore, the only way we can know the sacred law is from the revelation.” Other scholars said that qiyâs is not contrary to reason, but prohibited by the sacred law itself. Scott Lucas, when mentioning Ahmad Dallal’s position on Salafism, states that Dallal: ...declared that Salafism "is better understood as a method of thinking of, or an approach to, authoritative sources than as a distinct school of thought" that includes the elevation of the Quran and sound hadith at the expense of the opinions attributed to the eponyms of the four Sunni schools and the rejection (or sever curtailment) of qiyas Imam Bukhari Imam Bukhari maintained a negative position towards qiyas, as he held views aligned with the Zahiris of his time. Scott Lucas states that Bukhari’s rejection of qiyas was placed within the context of what Bukhari perceived as invalid techniques of ijtihad, which included religious innovation (bid’a), ra’y, and tamthil. Lucas also points out common mistakes other scholars make when analyzing Bukhari’s position on qiyas. The biggest source of confusion for scholars is the fact that, while rejecting qiyas, Bukhari accepts the idea of tashbih (comparison), which seems similar to analogy. However, this is not the case, as tashbih is a comparison used in explanation (such as a metaphor), whereas qiyas applies a specific legal ruling to another case. Bukhari is also known for his criticism of those who say that the Prophet used qiyas, and he devoted a section of his Sahih to the topic. Bukhari states: If the Prophet was asked about something about which he had not received a revelation, he either said, ‘I do not know’ or did not reply until he received a revelation. he did not [reply]
