I was reading the below Hadith:
Once Fatima came walking and her gait resembled the gait of the Prophet (ﷺ) . The Prophet (ﷺ) said, "Welcome, O my daughter!" Then he made her sit on his right or on his left side, and then he told her a secret and she started weeping. I asked her, "Why are you weeping?" He again told her a secret and she started laughing. I said, "I never saw happiness so near to sadness as I saw today." I asked her what the Prophet (ﷺ) had told her. She said, "I would never disclose the secret of Allah's Messenger (ﷺ)." When the Prophet (ﷺ) died, I asked her about it. She replied. "The Prophet (ﷺ) said: 'Every year Gabriel used to revise the Qur'an with me once only, but this year he has done so twice. I think this portends my death, and you will be the first of my family to follow me.' So I started weeping. Then he said. 'Don't you like to be the chief of all the ladies of Paradise or the chief of the believing women? So I laughed for that."
The bold sentence highlighted above makes we wonder if the order of the verses was divinely inspired and not put together by Caliph Umar (RA) as claimed by some.
Will it be more appropriate to think that the Sahaba knew the whole Quran by heart as it exists today and Caliph Umar (RA) only put it in a standard book format because he feared it may be lost/corrupted due to the large number of death of Huffaaz in a recent battle?
