Hadith on Anger: Seek refuge in Allah from Satan when he incites you with anger

Sulayman ibn Surad reported: Two people abused each other in the presence of the Messenger of Allah, peace and blessings be upon him, and the eyes of one of them became red like embers and the veins of his neck were swelling. The Prophet said, “Verily, I know a word he could say to calm himself: I seek refuge in Allah from the cursed Satan
أَعُوذُ بِاللَّهِ مِنْ الشَّيْطَانِ الرَّجِيمِ

The liar’s punishment is…

The liar’s punishment is, not in the least that he is not believed, but that he cannot believe anyone else.
