1- What is the role of women and children in Islam?
2- Is there any such thing as a ghost or spirit?
3- Why is it that Muslim people aren't allowed to date?
With regard to women, they have the same responsibilities as men; they have to call people to Allaah as much as they can, strive to call women and warn them against imitating the kuffaar, call them to acquire knowledge of Islam and to remember and worship Allaah, warn them against major and minor sins, and be a good example to others. This applies in all places where women meet.
With regard to children under the age of ten, their parents are responsible for striving to give them a good upbringing; if they make mistakes or do something that is haraam, then the sin is on the parents, because they should warn them to keep away from drugs, smoking and other things so that they will grow up healthy and sound.
Evil spirits are the spirits of the devils, and there are also devils among mankind who have been brought up to love evil and evildoers. They are the ones whose spirits emanate from their bodies and cause harm by means of the evil eye used against those whom they wish to harm. The jinn and the devils are evil and harmful spirits who may cause a great deal of harm to those who rely on them and trust them. But if a person is cautious about their evil, and seeks refuge with Allaah from the devils of mankind and the jinn, then Allaah will protect him and keep him safe from their evil.
Shaykh ‘Abd-Allaah ibn Jibreen
It is not permissible for a Muslim man to date a non-mahram woman and go out with her, because Allaah has forbidden the believers to do that as He says (interpretation of the meaning):
“Made lawful to you this day are At‑Tayyibaat [all kinds of Halaal (lawful) foods, which Allaah has made lawful (meat of slaughtered eatable animals, milk products, fats, vegetables and fruits)]. The food (slaughtered cattle, eatable animals) of the people of the Scripture (Jews and Christians) is lawful to you and yours is lawful to them. (Lawful to you in marriage) are chaste women from the believers and chaste women from those who were given the Scripture (Jews and Christians) before your time when you have given their due Mahr (bridal-money given by the husband to his wife at the time of marriage), desiring chastity (i.e. taking them in legal wedlock) not committing illegal sexual intercourse, nor taking them as girlfriends. And whosoever disbelieves in Faith, [i.e. in the Oneness of Allaah and in all the other Articles of Faith i.e. His (Allaah’s) Angels, His Holy Books, His Messengers, the Day of Resurrection and Al‑Qadar (Divine Preordainments)], then fruitless is his work; and in the Hereafter he will be among the losers”
And Allaah says (interpretation of the meaning):
“And when you ask (his wives) for anything you want, ask them from behind a screen, that is purer for your hearts and for their hearts”
And the Prophet (peace and blessings of Allaah be upon him) said: “No man is ever alone with a (non-mahram) women but the Shaytaan is the third one present.” (Narrated by al-Tirmidhi, 2165; classed as saheeh by al-Albaani in Saheeh al-Tirmidhi, 1758)
And Allaah is the Source of strength.
