Surah Maryam 19:45

يَـٰٓأَبَتِ إِنِّىٓ أَخَافُ أَن يَمَسَّكَ عَذَابٌ مِّنَ ٱلرَّحْمَـٰنِ فَتَكُونَ لِلشَّيْطَـٰنِ وَلِيًّا

O my father, indeed I fear that there will touch you a punishment from the Most Merciful so you would be to Satan a companion [in Hellfire]."

Translation: Saheeh International

Tafsir

O my father! I do fear lest a chastisement from the Compassionate One should befall you if you do not repent and then you become an ally of Satan an assistant and a comrade of his in the Fire.
