How can Islamic obligations evolve post-prophethood?
Q: In Islam, five foundational acts are considered obligatory, known as the Five Pillars: Shahadah, Salah, Zakat, Sawm, and Hajj. However, scholars from various schools of thought, such as Ibn Taymiyyah and Imam Abu Hanifa, have classified additional practices as farz (obligatory). For instance, the Eid prayers for Eid al-Adha and Eid al-Fitr are considered obligatory by some scholars, even though they were not explicitly declared as such by the Prophet Muhammad (peace be upon him). Given that the Prophet completed the teachings of Islam, as confirmed in the Quran, how can scholars add to what is considered farz after his lifetime? For example, Syed Muhammad Jaunpuri Mehdi AS also declared additional practices as farz, such as renunciation of the world (tark-e-Duniya) and other unique obligations. I’d like to understand why these additions can be regarded as farz, considering the Prophet didn’t specify them. Could you explain this concept…
