Verse 34 of Surah Luqman refers to five subjects, three of which are considered beyond the scope of human knowledge. Most commentators, citing a set of narrations, have considered “the descent of rain” and “the knowledge of what is in the Arham” as part of God’s exclusive unseen knowledge. However, these two subjects have faced an interpretive challenge with the advancement of empirical science and the possibility of predicting rain and determining the sex of the fetus for humans. This study has examined the narratives supporting this interpretation in three main categories: 1. deny anyone but God can know these things, 2. affirm God's exclusive knowledge over the five subjects, 3. deny the possibility of knowing them through astronomy. The findings show that the citation of these narrations is mainly rooted in Sunni sources, and the main motivation for the formation and spread of this interpretation was the use of the aforementioned verse in historical disputes with astronomers and to reject the "science of astronomical rulings"; which commonly involved predicting rain and fetal gender. In contrast, most prominent Shiite scholars have refrained from citing this verse when rejecting astronomy. Also, the chains of transmission for these narrations have weaknesses, and their application to the general concepts of the verse is challenging. The article concludes that the common understanding of the verse is mostly the product of the historical context and uncritical reliance on narrations, and a review of this interpretation is necessary considering the appearance of the verse.
