Though in England, Ayuba continued to pray regularly and observe his Islamic beliefs. He was said to have copied, by hand, the Quran three times from memory. His acquaintances made effort to convert him to Christianity, however, gifting him an Arabic version of the New Testament. Ayuba was already familiar with the Christian belief system, agreeing with the role of Jesus as prophet, but he refuted the concept of the holy Trinity. He considered his monotheistic perception of religion to be incompatible with the Christian belief in "the father," "the son," and "the holy spirit." He found the term "trinity" is not mentioned in the New Testament. He also advised against assignment of human images to God's name, and for this reason, displayed a particular disdain for Roman Catholicism and what he regarded as its characteristic worship of idols.
