I want to know the answer to the following question:
In which year did Abu Bakr die?
All the background I'm provided with is that "Based on earlier transmitted reports, in the year 632, after the demise of Muhammad a number of his companions who knew the Quran by heart were killed in a battle by Musaylimah, the first caliph Abu Bakr (d. 634) decided to collect the book in one volume so that it could be preserved.". Is that enough to answer the question?
