وَعَلَى ٱلثَّلَٰثَةِ ٱلَّذِينَ خُلِّفُوا۟ حَتَّىٰٓ إِذَا ضَاقَتْ عَلَيْهِمُ ٱلْأَرْضُ بِمَا رَحُبَتْ وَضَاقَتْ عَلَيْهِمْ أَنفُسُهُمْ وَظَنُّوٓا۟ أَن لَّا مَلْجَأَ مِنَ ٱللَّهِ إِلَّآ إِلَيْهِ ثُمَّ تَابَ عَلَيْهِمْ لِيَتُوبُوٓا۟ ۚ إِنَّ ٱللَّهَ هُوَ ٱلتَّوَّابُ ٱلرَّحِيمُ
And to the three also (did He turn in mercy) who were left behind, when the earth, vast as it is, was straitened for them, and their own souls were straitened for them till they bethought them that there is no refuge from Allah save toward Him. Then turned He unto them in mercy that they (too) might turn (repentant unto Him). Lo! Allah! He is the Relenting, the Merciful.
Surah At-Tawba(9:118)
