Feel overpowered by satan?

اعوذ بالله من الشيطن الرجيم

Surah 16. An-Nahl, Verse 99:

إِنَّهُ لَيْسَ لَهُ سُلْطَانٌ عَلَى الَّذِينَ آمَنُوا وَعَلَىٰ رَبِّهِمْ يَتَوَكَّلُونَ

Translation:

Verily! He has no power over those who believe and put their trust only in their Lord (Allah).

Surah 16. An-Nahl, Verse 100:

إِنَّمَا سُلْطَانُهُ عَلَى الَّذِينَ يَتَوَلَّوْنَهُ وَالَّذِينَ هُم بِهِ مُشْرِكُونَ

Translation:

His power is only over those who obey and follow him (Satan), and those who join partners with Him (Allah) [i.e. those who are Mushrikun - polytheists - see Verse 6:121].

Senility or infirmity of old age

اعوذ بالله من الشيطن الرجيم

Surah 16. An-Nahl, Verse 70:

وَاللَّهُ خَلَقَكُمْ ثُمَّ يَتَوَفَّاكُمْ وَمِنكُم مَّن يُرَدُّ إِلَىٰ أَرْذَلِ الْعُمُرِ لِكَيْ لَا يَعْلَمَ بَعْدَ عِلْمٍ شَيْئًا إِنَّ اللَّهَ عَلِيمٌ قَدِيرٌ

Translation:

And Allah has created you and then He will cause you to die, and of you there are some who are sent back to senility, so that they know nothing after having known (much). Truly! Allah is All-Knowing, All-Powerful.

Denying favours of Allah?

اعوذ بالله من الشيطن الرجيم

Surah 16. An-Nahl, Verse 71:

وَاللَّهُ فَضَّلَ بَعْضَكُمْ عَلَىٰ بَعْضٍ فِي الرِّزْقِ فَمَا الَّذِينَ فُضِّلُوا بِرَادِّي رِزْقِهِمْ عَلَىٰ مَا مَلَكَتْ أَيْمَانُهُمْ فَهُمْ فِيهِ سَوَاءٌ أَفَبِنِعْمَةِ اللَّهِ يَجْحَدُونَ

Translation:

And Allah has preferred some of you above others in wealth and properties. Then, those who are preferred will by no means hand over their wealth and properties to those (slaves) whom their right hands possess, so that they may be equal with them in respect thereof. Do they then deny the Favour of Allah?
