فَكَذَّبُوهُ فَنَجَّيْنَٰهُ وَمَن مَّعَهُۥ فِى ٱلْفُلْكِ وَجَعَلْنَٰهُمْ خَلَٰٓئِفَ وَأَغْرَقْنَا ٱلَّذِينَ كَذَّبُوا۟ بِـَٔايَٰتِنَا ۖ فَٱنظُرْ كَيْفَ كَانَ عَٰقِبَةُ ٱلْمُنذَرِينَ
But they denied him, so We saved him and those with him in the ship, and made them viceroys (in the earth), while We drowned those who denied Our revelations. See then the nature of the consequence for those who had been warned.

Sahih al-Bukhari
Companions of the Prophet
Chapter: The merits of 'Ali bin Abi Talib رضي الله عنه
Narrated Salama:
`Ali happened to stay behind the Prophet (ﷺ) and (did not join him) during the battle of Khaibar for he was having eye trouble. Then he said, "How could I remain behind Allah's Messenger (ﷺ)?" So `Ali set out following the Prophet (ﷺ) , When it was the eve of the day in the morning of which Allah helped (the Muslims) to conquer it, Allah's Messenger (ﷺ) said, "I will give the flag (to a man), or tomorrow a man whom Allah and His Apostle love will take the flag," or said, "A man who loves Allah and His Apostle; and Allah will grant victory under his leadership." Suddenly came `Ali whom we did not expect. The people said, "This is `Ali." Allah's Messenger (ﷺ) gave him the flag and Allah granted victory under his leadership.
