“And if an evil whisper comes to you from Satan, then seek refuge with GOD. Indeed, GOD is All-Hearer, All-Knower;” Quran 7:200.
GOD encourages lenient treatment of evil doers, for this might deter them from persistence in their evil, GOD Willing,
(then verily he, between whom and you there was enmity, (will become) as though he was a close friend), Quran 41:34.
GOD also encourages seeking refuge with Him from the devils of the Jinn. The devil will not be deterred if one is lenient with him, because he seeks your destruction and total demise. The devil to you, O mankind, is an open enemy, just as he was for your father before you.
Ibn Jarir said, while explaining the statement of GOD:
(And if an evil whisper comes to you from Satan). “If the devil lures you to get angry, thus directing you away from forgiving the ignorant and towards punishing him: فَاسْتَعِذْ بِاللهِ
(then seek refuge with GOD.)
GOD commands here to seek refuge with Him from the devil’s whispers: إِنَّهُ سَمِيْعٌ عَلِيْمٌ
(Verily, He is All-Hearer, All-Knower.) GOD hears the ignorance that the fools subject you to, your seeking refuge with Him from the devil’s whispers, and the rest of the speech of His creation; none of it escapes His Knowledge. He knows what drives the lures of the devil away from you, as well as, the rest of what His creatures do.”
“If a suggestion from Satan assaults your (mind), seek refuge with GOD; for He hears and Knows (all things).”
“Those who fear GOD, when a thought of evil from Satan assaults them, bring GOD to remembrance, when lo they see (aright)!” Quran 7:200-201.
