(Ambiya') 21 : 75
وَأَدْخَلْنَاهُ فِي رَحْمَتِنَا ۖ إِنَّهُ مِنَ الصَّالِحِينَ
And We admitted him into Our Mercy; Indeed, he was among the righteous.
Mercy is one of the 40 names of Adhikr. Lord will select that righteous person who lives under the Light of Adhikr as explained in verse 7: 196. See explanation 4: 69-70; 10: 57-58 and 11: 118.
