The Hour is only known to Allah – Mustafa al-Bughaa
In the sharh of the 40 hadiths of Imam Nawawi called “al-waafi”, the Arabic scholars Dr. Mustafa Dib al-Bughaa and Muhyi ad-Din Mistu wrote on page 19:
The hour and its signs: the knowledge of the time of the day of judgment is specificied with the knowledge of Allah, and he did not reveal it to ANYONE of his creation, whether an angel or a prophet. That is why the Prophet (salllaAllahy alayhi wa sallam) said to Jibril: The one who asked this question does not know more than who is asking the question.
