Please, are these hadiths authentic/reliable?
Abdullaah ibn ʻAbbaas narrated, "Abdullaah ibn Abi Sarh used to write (the revelation) for the Messenger of Allaah, sallallaahu 'alayhi wa sallam. Satan made him slip, and he joined the infidels. The Messenger of Allaah, sallallaahu 'alayhi wa sallam, commanded to kill him on the day of the Conquest (of Makkah). ‘Uthman ibn ‘Affaan sought protection for him. The Messenger of Allaah, sallallaahu 'alayhi wa sallam, gave him protection."
‘Uthman bin Abi Shaybah related to us that Ahmad bin Al-Mufadd related to us that Asb bin Nas related to us saying: Al-Suddi claimed from Mus‘ab bin Sa‘d from Sa‘d, who said:
"On the day of the Conquest of Makkah, ‘Abdullaah bin Abi Sarh hid with ‘Uthmaan bin ‘Affaan. He came with him and made him stand before the Prophet, sallallaahu 'alayhi wa sallam, and then said, 'O Messenger of Allaah! Accept the allegiance of ‘Abdullaah.' He raised his head three times, each time refusing him. Then he accepted his allegiance after the third time. He then turned to his Companions and said, 'Was there not among you a right-minded man who would have stood up to this one when I withheld my hand from accepting his allegiance and killed him?' They said, 'We did not know what you were thinking in your heart, O Messenger of Allaah! Why did you not give us a signal with your eye?' He said, 'It is not fitting for a prophet to wink.'" (Abu Da`ud 3793; seealso Nasa`i 3999)
All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah and that Muhammad is His slave and Messenger.
The report narrated on the authority of Ibn ʻAbbaas was cited by Abu Daawood and An-Nasaa'i; Al-Albaani declared its chain of narration authentic, as cited in his book Saheeh wa Dhaʻeef Sunan An-Nasaa'i.
The second hadeeth was cited by Abu Daawood and An-Nasaa'i, as narrated on the authority of Saʻad ibn Abi Waqqaas . Al-Haakim declared it saheeh (sound), and so did Ath-Thahabi and Ibn Al-Mulaqqin in his book Al-Badr Al-Muneer, and so did Al-Albaani.
Allaah knows best.
