Concept:The compilation of the Qur'ān into a single book relied on verifying written fragments against the oral testimony of memorizers.
Explanation:After the death of the Prophet (S.A.W), the Qur'ān existed in both written and memorized forms.
During the caliphate of Abū Bakr, Zayd bin Thābit was tasked with collecting these materials.
To ensure every verse was authentic, he cross-checked each written extract with the texts recalled from memory by early memorizers.
This was necessary because the Prophet (S.A.W) himself was unlettered and did not personally write the revelations.
Therefore, the written records alone were not trusted until they matched the memorized words of reliable companions.
This careful method preserved the Qur'ān's accuracy and authenticity.
Answer:The extracts were cross-checked with texts recalled from memory by early memorizers.
