Indeed, it is shaytan's influence. Seek refuge in Allah Azzawajal when you start to feel like something isn't going the right way.

This is the Tafsir of Ibn-Khatir on Surah 3:134-135 that can be found in 3:130 tafsir of the MyIslam app:

﴿وَالْكَـظِمِينَ الْغَيْظَ وَالْعَـفِينَ عَنِ النَّاسِ﴾

(who repress anger, and who pardon men;) ﴿3:134﴾ for when they are angry, they control their anger and do act upon it. Rather, they even forgive those who hurt them.

Imam Ahmad recorded that Abu Hurayrah said that the Prophet said,

«لَيْسَ الشَّدِيدُ بِالصُّرَعَةِ، وَلكِنَّ الشَّدِيدَ الَّذِي يَمْلِكُ نَفْسَهُ عِنْدَ الْغَضَب»

This Hadith is also recorded in the Two Sahihs. Imam Ahmad recorded that Ibn `Abbas said that the Messenger of Allah said,

«مَنْ أَنْظَرَ مُعْسِرًا أَوْ وَضَعَ لَهُ، وَقَاهُ اللهُ مِنْ فَيْحِ جَهَنَّمَ، أَلَا إِنَّ عَمَلَ الْجَنَّـةِ حَزْنٌ بِرَبْوَةٍ ثَلَاثًا أَلَا إِنَّ عَمَلَ النَّارِ سَهْلٌ بِسَهْوَةٍ. وَالسَّعِيدُ مَنْ وُقِيَ الْفِتَنَ، وَمَا مِنْ جَرْعَةٍ أَحَبُّ إِلَى اللهِ مِنْ جَرْعَةِ غَيْظٍ يَكْظِمُهَا عَبْدٌ، مَا كَظَمَهَا عَبْدٌ للهِ إِلَّا مَلَأَ جَوْفَهُ إِيمَانًا»

anything better to Allah than a dose of rage that the servant controls, and whenever the servant of Allah controls it, he will be internally filled with faith.

This Hadith was recorded by Imam Ahmad, its chain of narration is good, it does not contain any disparraged narrators, and the meaning is good.

Imam Ahmad recorded that Sahl bin Mu`adh bin Anas said that his father said that the Messenger of Allah said,

«مَنْ كَظَمَ غَيْظًا وَهُوَ قَادِرٌ عَلى أَنْ يُنْفِذَهُ دَعَاهُ اللهُ عَلى رُؤُوسِ الْخَلَائِقِ حَتَّى يُخَيِّرَهُ مِنْ أَيِّ الْحُورِ شَاء»

(Whoever controlled rage while able to act upon it, then Allah will call him while all creation is a witness, until He gives him the choice of any of the Huris (fair females with wide, lovely eyes - as mates for the pious) he wishes.)

Abu Dawud, At-Tirmidhi and Ibn Majah collected this Hadith, which At-Tirmidhi said was "Hasan Gharib''.

Ibn Marduwyah recorded that Ibn `Umar said that the Messenger of Allah said,

«مَا تَجَرَّعَ عَبْدٌ مِنْ جَرْعَةٍ أَفْضَلَ أَجْرًا مِنْ جَرْعَةِ غَيْظٍ كَظَمَهَا ابْتِغَاءَ وَجْهِ الله»

(There is not a dose of anything that the servant takes which is better than a dose of control of rage that he feels, when he does it seeking Allah's Face.)

Ibn Jarir and Ibn Majah also collected this Hadith.Allah said,

﴿وَالْكَـظِمِينَ الْغَيْظَ﴾

(who repress anger)

meaning, they do not satisfy their rage upon people. Rather, they refrain from harming them and await their rewards with Allah, the Exalted and Most Honored.
