Saba · 34:21Makkah

Shaytan has no real authority, only a test.

Whispers that reveal who believes

What Iblis has
no authorityno proof, no force
only
a testwho believes in the Hereafter
Allah guardsover all things
How strong is he
he made me do it
he only invitedI chose

Ibn 'Abbas said Iblis had no proof over them. He was allowed to whisper only to make clear who believes in the Hereafter and who doubts it. Ibn Kathir adds that by Allah's watching and care, the believers who follow the Messengers are saved.

You slip, and you blame the devil, the mood, the late night. Shaytan whispered, yes. But he has no power to force you. Every whisper is a question, and you give the answer.

When I give in to temptation, it is because Shaytan is too strong.

Shaytan only whispers. The choice is mine, and Allah guards those who turn to Him.

Tafsir Ibn Kathir (shared passage from 34:20)

And indeed Iblis did prove true his thought about them, and they followed him, all except a group of true believers (20)And he had no authority over them, – except that We might test him who believes in the Hereafter, from him who is in doubt about it. And your Lord is Watchful over everything (21)

How Iblis' thought about the Disbeliever proved True

Having mentioned Saba' and how they followed their desires, and the Shaytan, Allah tells us about their counterparts among those who follow Iblis and their own desires, and who go against wisdom and true guidance. Allah says:

وَلَقَدْ صَدَّقَ عَلَيْهِمْ إِبْلِيسُ ظَنَّهُ

(And indeed Iblis did prove true his thought about them,) Ibn 'Abbas, may Allah be pleased with him, and others said that this Ayah is like the Ayah where Allah tells us about how Iblis refused to prostrate to Adam, peace be upon him, then said:

أَرَأَيْتَكَ هَٰذَا الَّذِي كَرَّمْتَ عَلَيَّ لَئِنْ أَخَّرْتَنِ إِلَىٰ يَوْمِ الْقِيَامَةِ لَأَحْتَنِكَنَّ ذُرِّيَّتَهُ إِلَّا قَلِيلًا 

(See this one whom You have honored above me, if You give me respite to the Day of Resurrection, I will surely seize and mislead his offspring all but a few!)(17:62)

ثُمَّ لَآتِيَنَّهُمْ مِنْ بَيْنِ أَيْدِيهِمْ وَمِنْ خَلْفِهِمْ وَعَنْ أَيْمَانِهِمْ وَعَنْ شَمَائِلِهِمْ ۖ وَلَا تَجِدُ أَكْثَرَهُمْ شَاكِرِينَ 

(Then I will come to them from before them and behind them, from their right and from their left, and You will not find most of them as thankful ones.)(7:17) And there are many Ayat which refer to this matter.

وَمَا كَانَ لَهُ عَلَيْهِمْ مِنْ سُلْطَانٍ

(And he (Iblis) had no authority over them,) Ibn 'Abbas, may Allah be pleased with him said, "This means, he had no proof."

إِلَّا لِنَعْلَمَ مَنْ يُؤْمِنُ بِالْآخِرَةِ مِمَّنْ هُوَ مِنْهَا فِي شَكٍّ

(except that We might test him who believes in the Hereafter, from him who is in doubt about it.) means, 'We gave him power over them only to show who believes in the Hereafter and that it will come to pass.' The people will be brought to account and rewarded or punished accordingly, so that he will worship his Lord properly in this world – and to distinguish these believers from those who are in doubt about the Hereafter.

وَرَبُّكَ عَلَىٰ كُلِّ شَيْءٍ حَفِيظٌ

(And your Lord is a Watchful over everything.) means, despite His watching, those who follow Iblis go astray, but by His watching and care, the believers who follow the Messengers are saved.
