It has become common, of late, for people to recite the Qur'ân in a style that comprises a lot of affected weeping. Their recitation loses its sweetness as a consequence. It is closer to wailing than to a recitation. What do Islamic teachings say about this approach to reciting the Qur'ân?

What are the Virtues of the Day of Arafaah?

What is the ruling on one who delays Hajj for no reason when he has the means and is able to do it?

I have a few questions concerning parents:
1. What right does my Mother have over me? 
2. What right do I have over my mother? 
3. What do I have the freedom to do (which is Halal or Mubah, Ofcourse) without my Mother having the right to stop me? 
4. When does the Father have the final say in a matter? 

I love my mother very very very much. She is very over protective, and sometimes I feel like I'm in chains. I know she is doing it out of extreme love for me. How can I tell her that I need a little choice of my own in life.

Is it true that the person who is used to studying in Islamic schools, and has no previous experience of studying in non-Islamic schools, will never be able to connect with the environment that surrounds him, where most of the people are non-Muslims and that he will grow up shy and will never find any way to succeed either in his academic life or in the workplace? What is your opinion about that?

I want to make my children keen to pray, because they will pray once then forget about prayer many times. I always advise them and pray to Allah to guide them. How can I encourage them and make them love prayer?.

A non-Muslim friend of mine asked how I could prove the existence of God and why He has given us life, and what its purpose is?
My answer did not satisfy him, please tell me what I should tell him?

Our daughter is having strange experiences during sleep. She complains of feeling something pressing down on her chest which paralyzes her entire body. She cannot even speak. This stops and starts throughout the night. It happens so frequently that she has become depressed and angry. We feel that this is an attack from the Jinn and we want to know what she can do about it.

We celebrate the birthday of Prophet Muhammad (peace be upon him). On this day, we read a lot of salutations on him and engage in a lot of prayers to Allah. We try to show our love for our Prophet (peace be upon him). How come you say we cannot do it?
 

A young man proposed to a girl, but when the marriage contract was done, the girl’s father had a disagreement with his daughter’s fiancé, and refused to do the marriage contract. But the girl, her mother and her brother wanted the marriage to go ahead, so they left their house and rented an apartment, and they left the father who refused to do the marriage contract, and the marriage contract was done; the maternal uncle of the girl was the one who acted as her guardian (wali) in this marriage contract, in the presence of her brother. They argued that the father does not pray and they did not want him to be the wali of his daughter. How valid is this marriage contract?
