Christianity is a religion based on the life and teachings of Jesus of Nazareth, as described in the New Testament. Its adherents, known as Christians, believe that Jesus Christ is the Son of God and savior of all people, whose coming as the Messiah was prophesied in the Old Testament.
Quran is the greatest miracle in the whole history of the world, which proves that it can never be made by any one but Allah with His unlimited powers and unlimited Knowledge.
Miracle is something that people can not do it e.g. Prophet Jesus was granted by Allah the ability to revive the dead and cure the cureless. His miracles were limited to his time and no one can witness any of Jesus miracles now. The miracles of Quran is everlasting and can be witnessed by any one, any where and any time. Quran has challenged its enemies who used to claim that it was made by Muhammad, to bring like Quran even if the gather all their allies and supporters from Jinns and humans. The enemies of Quran failed to stand to the challenge. Allah then challenged them to bring ten chapters like the chapters of Quran which are 114 chapters. They failed again. Then Allah challenged them to bring just one chapter like any of the 114 chapters of Quran. They failed again. This challenge has proven that Quran is never from any human source otherwise the enemies of Quran could have brought anything like it even one chapter like any of its 114 chapters. Millions of Arabs today are non Muslims and they know the Arabic language very well, yet none of them could make even one line like Quran. This is an evidence which is enough for any one who thinks in proper way.
Quran was revealed on the Prophet Muhammad (SAWA) from Allah (SWT) and the allegation of obtaining it from Christians and Jewish communities has no scientific value at all, when you read Quran and compare it with the Jewish and Christian texts. Some similarities are there because the common origin of all the three texts is from Allah, but Torah and Bible were distorted while Quran remained remained constant and unchanged.
First of all, she needs to understand the basics of the faith of Islam; No God but Allah and Muhammad is His messenger. When she believes in Islam, permanent marriage between you and her will be allowed. No need for any witness from her family to attend. Marriage ceremony can be recited by any person who knows how to recite it in Arabic.
Whether the man will let her practice the religion or not is irrelevant and such marriage isn't permitted under Islamic law unless he would become Muslim.
May Allah grant you success
If all other shar'i requirements are met, yes, she can marry that man.
The marriage proposal must take its normal procedure, primarily around the parents giving their consent and their blessings. This is the most important part.
A second important step is to see the character traits of the person, their moral standards, their family, compatibility, etc.
A third step to take is seeking consultation and advice, trying to find out if this prospect marriage is a good idea, and the obstacles they might face. This is necessary for any case of marriage, Muslim born, or convert.
Both of them should study this from all its angles, for the sake of making the right decision and having a successful marriage.
With prayers for your success.
Your late wife must have been a good lady for you to continue to remember her. Yes, of course you can do dua and pray for her forgiveness, as long as she was not hostile to Islam and she knew no better.
With prayers for your success.
Islam preaches inner and outer modesty, and as human beings, we feel more safe and secure when we are covered up. This is why all religions somehow promote covering up and not being exposed for onlookers to see.
If a non-Muslim wishes to dress modestly, then of course that will benefit her. If she wishes to dress like a nun, or as Muslims, then that is also her choice, and it would not be considered as being 'inappropriate'.
In the case of a Muslim woman, or non-Muslim, wanting to, for example, enter into a holy shrine, there is a requirement that she does wear an abayah/chador. It is not Islamically mandated, but just out of respect.
And Allah knows best.
Real Christians are those who follow the real teachings of Jesus Christ. Jesus Christ gave the good news of the Messenger after him who is called Ahmad. Old bibles have this fact despite changes made many to hide it in other versions of bible.
Islam is the real message from God Almighty which is sent to all human beings. Jesus Christ wants people to follow the message of God. More details can found in many specialised websites. If she has specific questions she is welcome to write.
Islam is the religion of mercy.
Islam teaches us that we are responsible to others. We must be kind to God's creatures. Whenever the Qur'an advises us to donate, it does not make it specific to Muslims.
Yes, if you have to choose between a poor believer and an infidel, it is preferable to help the believer.
What evidence does she have that she saw Virgin Mary herself or what she imagined as Virgin Mary?
Many people think and imagine according to their thinking. We can not take their claim as reality.
Temporary marriage can only be performed with a woman who is from Ahlul Kitab, i.e. she is either a Muslim, a Christian or a Jew.
If she is of any other faith, or just believes in a supreme being, but does not follow any of the 3 Abrahamic religions, then you cannot do mut'ah with her.
And Allah knows best.
Quran has challenged all those who claimed what this person is claiming, to bring like Quran. ( Say: If the human beings and the Jinn join together to bring like this Quran, they will never bring like Quran even if all of them support each other.( Sura 17, Verse88).
If Quran is not the original word of God, then it should be possible for the enemies of Quran to produce like Quran. When they failed to do that, it means that Quran is the word of God.
After failing to bring like Quran which is from 114 chapters , Quran challenged the enemies to bring just ten chapters like Quran.( Or they say: He (Prophet Muhammad) fabricated it (Quran). Say: Then you bring ten fabricated chapters like its chapters, and seek help from whom you want apart from Allah, if you are truthful. (Sura 11, verse 13).
They again failed to face this challenge, which proved that Quran is not from any human source but from God.
Quran challenged them again to bring just one chapter like Quran.
(And if you are in doubt about what we revealed (Quran) on Our servant (Muhammad), then bring one chapter like Quran's chapters, and call all your partners and supporters besides Allah if you are truthful). (Sura 2, verse 23)
All these challenges were since over 1400 years, against all the enemies of Quran, but not a single response has come from them. This fact itself stands as a living evidence that Quran is The True Word of God and all claims of the enemies are false.
We put this fact in front of all enemies of Islam and ask them to produce even one chapter like Quran if their claims are right.
Last note for the person who claims to be a Christian yet accuses Quran, to deal with enemies of Jesus and his mother Mary who accuse Mary with false allegations with out any evidence. They are in fact doing wrong and misleading themselves and others. He is in fact doing the same by accusing Quran, The True and Original word of God.
We also invite him to read what the great scientists stated about Quranic verses including scientific facts which were impossible to be known before 1400 years but mentioned in Quran. Many books were written in this subject. Just search for: scientific miracles in Quran. You read and think between you and God and decide whether you really want to follow the Truth?
According to Islamic theology, every being that is not Allah is a created being that is not eternal or infinitely pre-existing. This includes angels and spirits and other non-visible or non-human beings. In fact, in this regard, one can say it is the main difference between Islamic and Christian theology.
According to Shi'i theology, there is a phase of existence that was "before" the material world (for instance, where the light of the Prophet (S) was created), however that phase was also created and everyone and everything in it was also created.
(Not sure if that answer helps!)
