وَرَبُّكَ ٱلْغَفُورُ ذُو ٱلرَّحْمَةِ ۖ لَوْ يُؤَاخِذُهُم بِمَا كَسَبُوا۟ لَعَجَّلَ لَهُمُ ٱلْعَذَابَ ۚ بَل لَّهُم مَّوْعِدٌۭ لَّن يَجِدُوا۟ مِن دُونِهِۦ مَوْئِلًۭا
Thy Lord is the Forgiver, Full of Mercy. If He took them to task (now) for what they earn, He would hasten on the doom for them; but theirs is an appointed term from which they will find no escape.

Narrated Anas bin Malik:
The Prophet (ﷺ) said to Ubai, "Allah has ordered me to recite to you: 'Those who disbelieve (Surat-al- Bayina 98).' " Ubai said, "Has He mentioned my name?" The Prophet (ﷺ) said, "Yes." On hearing this, Ubai started weeping.
