What is the longest period of pregnancy, and is there a contradiction between what scholars have mentioned regarding the maximum duration of pregnancy and medical evidence and the noble verse: "and his carrying and his weaning is thirty months"?

The opinions of jurists regarding the maximum duration of pregnancy vary between nine months and no limit for the maximum duration of pregnancy. Meanwhile, contemporary doctors believe it ranges between 10 months and 330 days, and most personal status laws define it as one year. Many contemporary researchers have rejected the idea of pregnancy extending for years, considering that long durations are rare and that the prevailing cases are what matter. Some believe that this issue depends on custom and experience, and that religion cannot contradict scientifically established reality.
