I want to know the answer to the following question:
What do Bohras believe happened to Taiyab abi al-qasim?
All the background I'm provided with is that "After his death, they believe their 21st Imam Taiyab abi al-Qasim went into a Dawr-e-Satr (period of concealment) that continues to this day.". Is that enough to answer the question?
Answer: yes
