For almost four hundred years, not many people among the Christians had even heard of the Trinity. That Council of Nicaea, which was actually boycotted by many Christian churches around the world, was called for by the Byzantine emperor Constantine I (288 - 337 A.D.), or Constantine the Great, who built the now Turkish city Constantinople in 330 A.D. to dedicate it to Jesus' mother, Virgin Mary.

This incident is included in the books of both Imam Ahmad and al-Tirmithi, each detailing it in his own Sahih book. And she bore patiently in the face of persecution to which her revered husband and his small band of believers were exposed at the hands of the polytheists and aristocrats of Quraish, sacrificing her vast wealth to promote Islam, seeking Allah's Pleasure.
