Al-Juwayni, a Sunni jurist and Mutakallim, or scholar engaged in the study of theological principles, spent his life deciphering between what a Muslim ought and ought not to do. He was said to be stubborn and accepting of any legal speculation whatsoever. His basic principle was that the law should not be left to speculation on any grounds. Rather, texts hold the answers to any possible legal debate in some capacity or another.^[7] He was a master of the Koran and Hadith texts in addition to being well versed in the particular school of Shafi'i and theological practices of the Ash'arite persuasion.^[10]
