Sex Education:
Islam commands sex purity, for men and for women, at all times,-before marriage, during marriage, and after the dissolution of marriage. Those guilty of illicit practices are shut out of the marriage circle of chaste men and women.
The Holy Quran says:
"Let no man guilty of adultery or fornication marry any but a woman similarly guilty or an Unbeliever nor let any but such a man or an Unbeliever marry such a woman: to the Believers such a thing is forbidden."(24.3)
"Women impure are for men impure and men impure are for women impure; and women of purity are for men of purity and men of purity are for women of purity: these are not affected by what people say: for them there is forgiveness and a provision honorable." (24.26)
The Prophet (Peace be upon him) said: 'Whoever guarantees me (the
chastity of) what is between his legs (i.e. his private parts), and what
is between his jaws (i.e., his tongue), I guarantee him Paradise.'
Women's courses
The Holy Quran says:
"They ask thee concerning women's courses. Say: They are a hurt and a pollution; so keep away from women in their courses and do not approach them until they are clean. But when they have purified themselves ye may approach them in any manner time or place ordained for you by Allah. For Allah loves those who turn to Him constantly and He loves those who keep themselves pure and clean." (2.222 )
Allah's Messenger (Peace be upon him) said: 'When someone with whose religion and character you are satisfied asks your daughter in marriage, accede to his request. If you do not do so, there will be temptation on Earth and extensive corruption.' (Narrated by Abu Hurayrah)
I heard Allah's Apostle (Peace be upon him) saying: 'From among the portents of the Hour are the following: Religious knowledge will be taken away; general ignorance (in religious matters) will increase; illegal sexual intercourse will prevail; drinking of alcoholic drinks will prevail. Men will decrease in number, and women will increase in number, so much so that fifty women will be looked after by one man.' (Narrated by Anas)
The Holy Prophet said, "If lewdness exists among people and then appears as a common and open practice, plagues and new diseases which did not exist before will spread among them".(Narrated in Ibn Maajah)
This saying of Prophet Muhammad (Peace be upon him) point outs towards the modern diseases like HIV, AIDS etc. Not to forget that Muhammad (Peace be upon him) had told about it 1400 years ago.
The Holy Quran says:
"Nor come nigh to adultery: for it is a shameful (deed) and an evil opening the road (to other evils)." (17.32 )
Allah's Apostle (Peace be upon him) said: 'When a slave (of Allah) commits illegal sexual intercourse, he is not a believer at the time of committing it.'
The Prophet (Peace be upon him) said: 'The one who commits an illegal sexual intercourse is not a believer at the time of committing illegal sexual intercourse.'
