Screening tests in pregnancy
Question

                As you know, screening tests or diagnostic tests to check for severe handicap in the fetus are usually performed early in pregnancy with the objective of possible termination of the pregnancy at approx 19 weeks of pregnancy.  I would like to enquire if this is advisable in the Islamic Faith?
Praise be to Allah.Yes, 
          that is permissible, but with regard to aborting the foetus, some scholars 
          have allowed that under certain conditions: 
1-That the soul should not yet have entered the foetus, i.e. within 
          the first four months of the pregnancy from the time of conception. 
          
2-There should be a necessary reason for doing so, such as handicap 
          or deformity which is discovered in the pregnancy, or a risk to the 
          mother. At the same time, if a person can be patient and put his trust 
          in Allaah, that will be better for him with his Lord.

 But 
          it is essential to note that the doctors may be mistaken in their reports 
          and that the test results are often imprecise. So we must be very careful 
          when taking serious decisions such as deciding to abort a pregnancy 
          on the basis of such reports. Some shortcomings in a newborn may be 
          made up later on, or a fault may be removed and the child may be born 
          healthy. If we assume that the child is born at full term with a deformity, 
          then bearing that with patience and seeking the reward of Allaah by 
          caring for the child will not be lost with Allaah. It will not be a 
          loss, as it is viewed by many materialists, some of whom want to kill 
          the handicapped because they are a burden on society. Allaah is Most 
          Wise in all that He creates and decrees, may He be glorified and exalted.
