According to the consensus of classical Islamic scholarship, any attempt to learn of the unseen through divination is categorically forbidden (haram) and considered a grave sin that compromises the core of a Muslim's faith. The Quran, in Surah Al-Ma'idah (5:3, 5:90), explicitly prohibits practices like *al-istiqsam bil-azlam* (seeking decisions by divining arrows), labeling them an 'abomination of Satan's handiwork' and an act of impiety. Tafsir authorities like Ibn Kathir explain this was a pre-Islamic practice of fortune-telling that Islam abolished. This prohibition is theologically grounded in the principle that knowledge of the Unseen (al-Ghayb) belongs exclusively to Allah. Further verses (15:18, 37:8, 72:9) reinforce this by describing how the heavens are divinely guarded with 'flames' against jinn and devils who attempt to eavesdrop, proving the futility of such knowledge-seeking. Therefore, engaging in or believing in any form of divination, from ancient soothsaying to modern astrology, is seen as a violation of Tawheed (God's Oneness) and a denial of divine revelation.
