“Indeed, it is We who sent down the Quran and indeed, We will be its guardian.” - Quran 15:9
After the Prophet's (PBUH) passing, the Quran was compiled into a single manuscript during the caliphate of Abu Bakr (RA) and later standardized by Uthman (RA) to preserve its authenticity.
The compilation ensured the Quran would remain unchanged and accessible to all Muslims, uniting the ummah on a single text.
The standardized Quran was distributed to major Islamic cities, and all other versions were destroyed to prevent discrepancies.
