Virgin Mary is the Mother of Isa (AS) known as Jesus. She is regarded as an extremely important, pious, chaste figure in Islam so much so that an entire Chapter in the Holy Qur’aan (Chapter 19) is dedicated to her by name), there is no Chapter in the Qur’aan dedicated to the Mother of Prophet Muhammad (Peace be upon Him).
Islam frowns upon the concept of imagery and images and there is no scope in Islam for imagery. Worship is exclusively and solely devoted to Creator and no distractions are allowed therefore no images including that of Mary are permitted.
Again, worship is exclusive for God and servitude is the domain of humans. All humans are created equal and no subservience, devotion or servitude is permitted to anyone including Mary, Mother of or Prophet Muhammad (Peace be upon Him) himself.
The central concept in Islam is to worship ONE GOD. Prayers are not permitted to anyone besides Him, alone.
وَقَضَىٰ رَبُّكَ أَلَّا تَعۡبُدُوٓاْ إِلَّآ إِيَّاهُ وَبِٱلۡوَٲلِدَيۡنِ إِحۡسَـٰنًاۚ إِمَّا يَبۡلُغَنَّ عِندَكَ ٱلۡڪِبَرَ أَحَدُهُمَآ أَوۡ كِلَاهُمَا فَلَا تَقُل لَّهُمَآ أُفٍّ۬ وَلَا تَنۡہَرۡهُمَا وَقُل لَّهُمَا قَوۡلاً۬ ڪَرِيمً۬ا
[17:23] Your Lord has decreed that you worship none but Him, and do good to parents. If any one of them or both of them reach old age, do not say to them: uff (a word or expression of anger or contempt) and do not scold them, and address them with respectful words.
Next time, take a look around at the imagery in your Church and think about who follows in the footsteps of Virgin Mary? Muslim women or Christian women?
