And Noah cried unto his Lord and said: My Lord! Lo! my son is of my household! Surely Thy promise is the truth and Thou are the Most Just of Judges.

Sahih al-Bukhari
Prophetic Commentary on the Qur'an (Tafseer of the Prophet (pbuh))
Narrated Jubair bin Mut`im:
I heard the Prophet (ﷺ) reciting Surat at-Tur in the Maghrib prayer, and when he reached the Verse: 'Were they created by nothing, Or were they themselves the creators, Or did they create the Heavens and the Earth? Nay, but they have no firm belief Or do they own the treasures of Your Lord? Or have they been given the authority to do as they like...' (52.35-37) my heart was about to fly (when I realized this firm argument).
