Scholarly Insight: In Islamic theology (Aqeedah) and jurisprudence (Fiqh), the distinction between abandoning a pillar of Islam out of rejection (Juhood) versus laziness (Kasl) is crucial. Rejecting the obligation of Salah is a matter of consensus (Ijmaa') constituting major disbelief (Kufr Akbar), as it fundamentally belies the Quran and the Messenger. However, leaving it out of negligence while still believing in its obligation is where classic scholarly divergence (Ikhtilaf) occurs. The Hanbali school traditionally views it as disbelief, citing authentic Hadiths that equate abandoning prayer directly with disbelief, whereas the Shafi'i, Maliki, and Hanafi schools generally categorize it as a major sin (Kabeerah), emphasizing that foundational belief (Iman) remains intact, albeit severely compromised.
