hope after sin

فَتَلَقَّىٰٓ ءَادَمُ مِن رَّبِّهِۦ كَلِمَـٰتٍ فَتَابَ عَلَيْهِ ۚ إِنَّهُۥ هُوَ ٱلتَّوَّابُ ٱلرَّحِيمُ

Then Adam received from his Lord [some] words, and He accepted his repentance. Indeed, it is He who is the Accepting of Repentance, the Merciful.

ثُمَّ يَتُوبُ ٱللَّهُ مِنۢ بَعْدِ ذَٰلِكَ عَلَىٰ مَن يَشَآءُ ۗ وَٱللَّهُ غَفُورٌ رَّحِيمٌ

Then Allāh will accept repentance after that for whom He wills; and Allāh is Forgiving and Merciful.
