What is the ruling of Sharia on using IUD (Intrauterine device) temporarily and by mutual agreement of husband and wife?
All perfect praise be to Allah the Lord of the Worlds. May His peace and blessings be upon our Prophet Mohammad and upon all his family and companions.
There is nothing wrong with this if this device is used on temporary basis and by mutual agreement of husband and wife since this issue falls into family planning, which is allowed by Sharia. However, this is provided that the device is inserted by a female doctor and that it doesn`t cause harm to the woman. And Allah The Almighty Knows Best.
I`m a married young man. I fell in love with a widow and proposed to her but her family refused because they feared that this would have an adverse impact on the future of her children. However, we entered into unregistered marriage and told my family and even my wife about it. I`m a person who fears Allah, The Almighty and want to clear myself from any liability before Him, The Exalted. What should I do?
All perfect praise be to Allah the Lord of The Worlds. May His blessings and peace be upon our Prophet Mohammad and upon all his family and companions.
It is imperative that you proclaim this marriage to preserve rights. Therefore, you must register it in an Islamic court. A second marriage isn`t forbidden, however, if the unregistered marriage had taken place without the consent of the woman`s guardian nor the presence of two honorable witnesses, then it is considered void and your relationship with this woman is forbidden. Therefore, you must conclude a new marriage contract with the approval of her guardian and the presence of two honorable witnesses. We advise you to fear Allah and adhere to the teachings of Sharia in this regard since sinful conduct is that which turns in your heart (making you feel uncomfortable) and you dislike that it would be disclosed to other people. And Allah The Almighy Knows Best.
