Since the Father, Son and Holy Spirit are of one substance the math is:
1 x 1 x 1 = 1
not
1 + 1 + 1 = 3
Mohammad thought that Christians worshipped Mary with the Father and Son:
5.116
YUSUFALI: And behold! Allah will say: “O Jesus the son of Mary! Didst thou say unto men, worship me and my mother as gods in derogation of Allah’?” He will say: "Glory to Thee! never could I say what I had no right. Had I said such a thing, thou wouldst indeed have known it. Thou knowest what is in my heart, Thou I know not what is in Thine. For Thou knowest in full all that is hidden.
PICKTHAL: And when Allah saith: O Jesus, son of Mary! Didst thou say unto mankind: Take me and my mother for two gods beside Allah? he saith: Be glorified! It was not mine to utter that to which I had no right. If I used to say it, then Thou knewest it. Thou knowest what is in my mind, and I know not what is in Thy Mind. Lo! Thou, only Thou, art the Knower of Things Hidden?
SHAKIR: And when Allah will say: O Isa son of Marium! did you say to men, Take me and my mother for two gods besides Allah he will say: Glory be to Thee, it did not befit me that I should say what I had no right to; if I had said it, Thou wouldst indeed have known it; Thou knowest what is in my mind, and I do not know what is in Thy mind, surely Thou art the great Knower of the unseen things.
Literal:And when God said: “You Jesus Mary’s son, did you say to the people ‘Take me and my mother two gods from other than God?’ He said: ‘Your praise/glory, is not to be for me that I say what is not for me with right/truth, if I was said it, so You had known it, You know what in my self, and I do not know what in Your self, that You, You all knower the unseens/hidden.’”
**There was actually a grooup that did worship Mary the Collyridians, located in Arabia. **
Actually the word Trinity is a stretch here by Yusufali
4.171
YUSUFALI: O People of the Book! Commit no excesses in your religion: Nor say of Allah aught but the truth. Christ Jesus the son of Mary was a messenger of Allah, and His Word, which He bestowed on Mary, and a spirit proceeding from Him: so believe in Allah and His messengers. Say not “Trinity” : desist: it will be better for you: for Allah is one Allah: Glory be to Him: above having a son. To Him belong all things in the heavens and on earth. And enough is Allah as a Disposer of affairs.
PICKTHAL: O People of the Scripture! Do not exaggerate in your religion nor utter aught concerning Allah save the truth. The Messiah, Jesus son of Mary, was only a messenger of Allah, and His word which He conveyed unto Mary, and a spirit from Him. So believe in Allah and His messengers, and say not “Three” - Cease! better for you! - Allah is only One Allah. Far is it removed from His Transcendent Majesty that He should have a son. His is all that is in the heavens and all that is in the earth. And Allah is sufficient as Defender.
SHAKIR: O followers of the Book! do not exceed the limits in your religion, and do not speakagainst Allah, but the truth; the Messiah, Isa son of Marium is only a messenger of Allah and His Word which He communicated to Marium and a spirit from Him; believe therefore in Allah and His messengers, and say not, Three. Desist, it is better for you; Allah is only one Allah; far be It from His glory that He should have a son, whatever is in the heavens and whatever is in the earth is His, and Allah is sufficient for a Protector.
When you look up the literal translations of all the verses it is very telling.
Literal:You The Book’s people, do not exaggerate/exceed the limit in your religion, and do not say on God except the truth , but the Messiah, Jesus, Mary’s son God’s messenger and His word/expression He threw it away to Mary, and a Soul/Spirit from Him; so believe with God, and His messengers, and do not say: “Three.” Stop best for you, but God one God, His praise/glory that to be for him a child; for Him what in the skies/space and whatin the earth/Planet Earth, enough/sufficient with God guardian/protector .
See two say only a messanger and the literal says GOD’s messenger.
Which is true Jesus was a messenger with the best message ever!!
