As Salam alaykum please is these hadith authentic -
Haritha ibn Wahb reported: The Messenger of Allah, peace and blessings be upon him, said:
أَلَا أُخْبِرُكُمْ بِأَهْلِ الْجَنَّةِ كُلُّ ضَعِيفٍ مُتَضَعِّفٍ لَوْ أَقْسَمَ عَلَى اللَّهِ لَأَبَرَّهُ أَلَا أُخْبِرُكُمْ بِأَهْلِ النَّارِ كُلُّ عُتُلٍّ جَوَّاظٍ مُسْتَكْبِرٍ
Shall I not tell you about the companions of Paradise? They are every humble person considered weak, but if they gave an oath by Allah it would be fulfilled. Shall I not tell you about the companions of Hellfire? They are every harsh, haughty, and arrogant person.
Source: Sahih Bukhari 4634,

All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah, and that Muhammad is His slave and Messenger.

This Hadeeth is of the highest degree of authenticity. It was narrated on the authority of Haarithah ibn Wahb, may Allaah be pleased with him, that he said: “I heard the Prophet say: ‘Shall I inform you of the people of Paradise? Every weak and humble person, but if he were to take an oath by Allah (that something will or will not happen), it will be fulfilled by Allah. Shall I inform you of the people of the Hellfire? Every cruel, harsh, and arrogant (person).’” [Ahmad, Al-Bukhaari, Muslim, At-Tirmithi, An-Nasaa’i, and Ibn Maajah]

Allah Knows best.
