Does Maghfirah Non Quranic ?

[Sardar Miyan]

I came across a blog where it is said by an Alim that the word Maghfirah is Non Quranic which means that one can not pray  Allah for a diseased person for his salvation.or forgiving his shortcomings or sins? Thanks

21.رَبَّنَا وَأَدْخِلْهُمْ جَنَّاتِ عَدْنٍ الَّتِي وَعَدتَّهُم وَمَن صَلَحَ مِنْ آبَائِهِمْ وَأَزْوَاجِهِمْ وَذُرِّيَّاتِهِمْ إِنَّكَ أَنتَ الْعَزِيزُ الْحَكِيمُ
Surah al-Mu’min 40:8

Our Lord! Make them enter the Garden of Eden which You have promised to them, and to the righteous from among their fathers, their wives and their offspring, for verily You are alone the Almighty and the truly Wise.
