Francis’ April 3, 2019 discourse at his General Audience:
“I visited the Mausoleum [tomb] of Mohammed V where I paid homage to his memory and to that of Hassan II. I then visited the Institute for the formation of Imams and of men and women preachers. This Institute promotes an Islam which respects other religions… Muslims invoke the Clement and the Merciful One, every day.”
Francis pays homage to deceased Muslims and mentions that he visited the institute for the formation of Imams (Islamic leaders). As you can see above, Francis also laid a wreath of flowers in front of the tomb of Mohammed V.
St. Thomas Aquinas, Summa Theologica, Pt. II, Q. 12, A. 1, Obj. 2: “… if anyone were to… worship at the tomb of Mahomet, he would be deemed an apostate.”
Francis praises the Islamic institute because it respects other false religions. The apostate Francis says Muslims invoke the true God “every day”.
