Is it permissible to abort one of three fetuses in the seventh week to avoid premature birth and the problems associated with premature infants?

As long as these fetuses have not reached 120 days and the soul has not been breathed into them, there is no sin in aborting one of them if their continued presence together poses a danger to them, or causes harm to them or to the mother. The judgment on this matter refers to trustworthy and reliable doctors.
