(Qasas) 28 : 46
وَمَا كُنْتَ بِجَانِبِ الطُّورِ إِذْ نَادَيْنَا وَلَٰكِنْ رَحْمَةً مِنْ رَبِّكَ لِتُنْذِرَ قَوْمًا مَا أَتَاهُمْ مِنْ نَذِيرٍ مِنْ قَبْلِكَ لَعَلَّهُمْ يَتَذَكَّرُونَ

And you were not at the side of the mount when We called him! But It is the Mercy from your Lord to warn a people to whom no warner had come before you so that they might remind others in their heart’s language.

Mercy is one among the 40 names of Adhikr mentioned in 65 places such as in verses 2: 105; 4: 113; 10: 58 and 11: 118-119. See explanation 3: 10; 5: 86 and 22: 57.
