This website is reporting that before getting married, potential couples are getting tested for genetic disease: http://www.arabnews.com/saudi-arabia/news/844656
This is a program that the Ministry of Health in Saudi Arabia wants every one to participate in. This program is for those who are getting married to a cousin. So basically under the program, before getting married to a cousin, the parties involved in the marriage contract undergo genetic screening to see if the union might potentially result in progeny with higher chance of genetically induced diseases. There are two outcomes of this screening:
- The parties do not proceed with the marriage.
- If the parties do proceed with the marriage, the idea of the screening is that this program will help the couple plan for combating the disease.
Now my question: are the people involved in the program committing kufr or nullifying their iman because they're challenging Allah SWT?
My point being that a Muslim must expect the best from Allah. So the couple expects that even though there is a higher chance of genetic disease developing in their offspring, they hope that Allah will bless them with a healthy child. However, at the same time if he/she develops plans to be ready for any eventuality to combat the genetic disease, is he/she manifesting evil thoughts about Allah SWT and thereby committing kufr?
