On acting; and the ruling on marrying young girls

1)What is the ruling of islam acting in movies?.If it is allowed what type of filims must be them?.Also what is the role of women in movies ?.
2)Why islam allowed to marry children(girls) of age below 10 with out their permission(it is said that in the case of children,it requires the concern of their parents only.I also know it requires to get the permission in the case of adults).Actually marrage has to taken plce between the persons, who have even a little meturity.But in the case of children it not happend.Can you justify this ruling of islam(Child marrage ) ?.

Praise be to Allaah.  

Firstly: 

The question of acting and related issues has already been dealt with in Question no. 10836. We may add to that: 

Shaykh Abu Bakr Zayd (may Allaah preserve him) said: chivalry [i.e., behaving in a proper and decent manner] is one of the aims of sharee’ah, and anything that undermines that renders a person unfit to give testimony in court. Islam enjoins the loftiest characteristics and forbids base and vile characteristics. How often do viewers see an actor doing silly actions or moving or speaking in a silly manner, or even playing the role of a madman, idiot or fool. Based on this, it is clear to the wise man that acting is one of the things that most undermine chivalry, so it is one of the things that render a person unfit to give testimony in court. Anything that is like that is not approved of in sharee’ah. 

See al-Muru’ah wa Khawaarimuhaa, p. 221, by Mashhoor Hasan 

Secondly: 

Marrying a young girl before she reaches the age of adolescence is permitted in sharee’ah; indeed it was narrated that there was scholarly consensus on this point. 

(a)     Allaah says (interpretation of the meaning): 

“And those of your women as have passed the age of monthly courses, for them the ‘Iddah (prescribed period), if you have doubt (about their periods), is three months; and for those who have no courses [(i.e. they are still immature) their ‘Iddah (prescribed period) is three months likewise”

[al-Talaaq 65:4] 

In this verse we see that Allaah has made the ‘iddah in the case of divorce of a girl who does not have periods – because she is young and has not yet reached puberty – three months. This clearly indicates that Allaah has made this a valid marriage. 

(b)    It was narrated from ‘Aa’ishah (may Allaah be pleased with her) that the Prophet (peace and blessings of Allaah be upon him) married her when she was six years old, he consummated the marriage with her when she was nine and she stayed with him for nine years.

(Narrated by al-Bukhaari, 4840; Muslim, 1422) 

The Prophet (peace and blessings of Allaah be upon him) married ‘Aa’ishah when she was six years old and consummated the marriage when she was nine.”

(Narrated by al-Bukhaari and Muslim; Muslim says ‘seven years’) 

The fact that it is permissible to marry a young girl does not mean that it is permissible to have intercourse with her; rather that should not be done until she is able for it. For that reason the Prophet (peace and blessings of Allaah be upon him) delayed the consummation of his marriage to ‘Aa’ishah. Al-Nawawi said: With regard to the wedding-party of a young married girl at the time of consummating the marriage, if the husband and the guardian of the girl agree upon something that will not cause harm to the young girl, then that may be done. If they disagree, then Ahmad and Abu ‘Ubayd say that one a girl reaches the age of nine then the marriage may be consummated even without her consent, but that does not apply in the case of who is younger. Maalik, al-Shaafa’i and Abu Haneefah said: the marriage may be consummated when the girl is able for intercourse, which varies from one girl to another, so no age limit can be set. This is the correct view. There is nothing in the hadeeth of ‘Aa’ishah to set an age limit, or to forbid that in the case of a girl who is able for it before the age of nine, or to allow it in the case of a girl who is not able for it and has reached the age of nine. Al-Dawoodi said: ‘Aa’ishah (may Allaah be pleased with her) was reached physical maturity (at the time when her marriage was consummated). 

Sharh Muslim, 9/206 

It is preferable for a guardian not to marry off his daughter when she is still young unless there is a valid reason for that. 

Al-Nawawi said: 

It should be noted that al-Shaafa’i and his companions said: It is preferable for fathers and grandfathers not to marry off a virgin until she reaches the age of puberty and they ask her permission, lest she end up in a marriage that she dislikes. What they said does not go against the hadeeth of ‘Aa’ishah, because what they meant is that they should not marry her off before she reaches puberty if there is no obvious interest to be served that they fear will be missed out on if they delay it, as in the hadeeth of ‘Aa’ishah. In that case it is preferable to go ahead with the marriage because the father is enjoined to take care of his child’s interests and not to let a good opportunity slip away.

 And Allaah knows best.
