I watched a video by Anthony Roger's on Allah's hands being literal hands. He posted a source from Sahih Muslim 1827 but I couldn't find it on the old USC page, I did however find it in another place:
وَكِلْتَا يَدَيْهِ يَمِينٌ being the Arabic for "and both of his hands are right hands." This passage is graded "sahih" authentic.
Later, I found out that the same website contains it as listed under Sahih Muslim 1827 as mentioned by Anthony!
Turns out Christian prince has a video that discusses this.
The Prophet [SAW] said: "Those who are just and fair will be with Allah, Most High, on thrones of light, at the right hand of the Most Merciful, those who are just in their rulings and in their dealings with their families and those of whom they are in charge." Muhammad (one of the narrators) said in his Hadith: "And both of His hands are right hands."--Sunan an-Nasa'i 5379, Book 49, Hadith 1
أَخْبَرَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، قَالَ حَدَّثَنَا سُفْيَانُ، عَنْ عَمْرٍو، ح وَأَنْبَأَنَا مُحَمَّدُ بْنُ آدَمَ بْنِ سُلَيْمَانَ، عَنِ ابْنِ الْمُبَارَكِ، عَنْ سُفْيَانَ بْنِ عُيَيْنَةَ، عَنْ عَمْرِو بْنِ دِينَارٍ، عَنْ عَمْرِو بْنِ أَوْسٍ، عَنْ عَبْدِ اللَّهِ بْنِ عَمْرِو بْنِ الْعَاصِ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ " إِنَّ الْمُقْسِطِينَ عِنْدَ اللَّهِ تَعَالَى عَلَى مَنَابِرَ مِنْ نُورٍ عَلَى يَمِينِ الرَّحْمَنِ الَّذِينَ يَعْدِلُونَ فِي حُكْمِهِمْ وَأَهْلِيهِمْ وَمَا وَلُوا ". قَالَ مُحَمَّدٌ فِي حَدِيثِهِ " وَكِلْتَا يَدَيْهِ يَمِينٌ ".
Later, I found out that the same website contains it as listed under Sahih Muslim 1827 as mentioned by Anthony!
Behold! the Dispensers of justice will be seated on the pulpits of light beside God, on the right side of the Merciful, Exalted and GlorioUS. Either side of the Being is the right side both being equally mrneritorious. (The Dispensers of justice are) those who do justice in their rules, in matters relating to their families and in all that they undertake to do.--Sahih Muslim 1827
Despite the translation with the typos and omitting the mention of a hand, we see the same phrase being used وَكِلْتَا يَدَيْهِ يَمِينٌحَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، وَزُهَيْرُ بْنُ حَرْبٍ، وَابْنُ، نُمَيْرٍ قَالُوا حَدَّثَنَا سُفْيَانُ، بْنُ عُيَيْنَةَ عَنْ عَمْرٍو، - يَعْنِي ابْنَ دِينَارٍ - عَنْ عَمْرِو بْنِ أَوْسٍ، عَنْ عَبْدِ اللَّهِ بْنِ عَمْرٍو، قَالَ ابْنُ نُمَيْرٍ وَأَبُو بَكْرٍ يَبْلُغُ بِهِ النَّبِيَّ صلى الله عليه وسلم وَفِي حَدِيثِ زُهَيْرٍ قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " إِنَّ الْمُقْسِطِينَ عِنْدَ اللَّهِ عَلَى مَنَابِرَ مِنْ نُورٍ عَنْ يَمِينِ الرَّحْمَنِ عَزَّ وَجَلَّ وَكِلْتَا يَدَيْهِ يَمِينٌ الَّذِينَ يَعْدِلُونَ فِي حُكْمِهِمْ وَأَهْلِيهِمْ وَمَا وَلُوا " .
