Whoever turns from remembrance is assigned a shaytan as qareen

God informed in Surat al-Zukhruf that whoever turns away from the remembrance of the Merciful is assigned a shaytan who becomes his companion, until on the Last Day its owner says to the companion «would that the distance between me and you were the distance of east and west» — that is, would that the distance between us were that between east and west — and it is said to him «and evil is the companion» ¹ Zukhruf 36 Zukhruf 38; and in Surat al-Nisa «and whoever has the shaytan as companion, evil is the companion» ¹ Women 38.

In these ayahs, whoever turns away from the remembrance of God is assigned a companion from the shayatin who accompanies and misleads him — the same companion from whom its owner disowns himself on the Last Day ¹.

From the qareen ayahs of the Qur'an; the Jinn & Devils Browser shows it in the devils and jinn sections ¹.
