Someone who is consulted is in a position of trust

Abu Hurayra reported that the Prophet ﷺ asked Abu'l-Haytham:
"Do you have a servant?" "No," he replied. He said, "Come to us when we get some captives." The Prophet ﷺ was brought only two captives. Abu'l-Haytham came to him and the Prophet ﷺ said, "Choose between them." "Choose for me, Messenger of Allah," he replied. The Prophet ﷺ said, "The person who is consulted is in a position of trust. Take this one. I have seen him pray. Treat him well." Abu'l-Haytham's wife said, "You will not live up to the words of the Prophet ﷺ about him until you set him free." "He is free," he stated. The Prophet ﷺ said, "Allah did not send a Prophet or khalifa but that he has two confidants: a confidant who commands him to do what is correct and forbids what is bad, and a confidant who will not fall short in corrupting you. Anyone who is protected from the evil confidant has been protected."

حَدَّثَنَا آدَمُ، قَالَ: حَدَّثَنَا شَيْبَانُ أَبُو مُعَاوِيَةَ، قَالَ: حَدَّثَنَا عَبْدُ الْمَلِكِ بْنُ عُمَيْرٍ، عَنْ أَبِي سَلَمَةَ بْنِ عَبْدِ الرَّحْمَنِ، عَنْ أَبِي هُرَيْرَةَ قَالَ: قَالَ النَّبِيُّ ﷺ لأَبِي الْهَيْثَمِ: هَلْ لَكَ خَادِمٌ؟ قَالَ: لاَ، قَالَ: فَإِذَا أَتَانَا سَبْيٌ فَأْتِنَا فَأُتِيَ النَّبِيُّ ﷺ بِرَأْسَيْنِ لَيْسَ مَعَهُمَا ثَالِثٌ، فَأَتَاهُ أَبُو الْهَيْثَمِ، قَالَ النَّبِيُّ ﷺ: اخْتَرْ مِنْهُمَا، قَالَ: يَا رَسُولَ اللهِ، اخْتَرْ لِي، فَقَالَ النَّبِيُّ ﷺ: إِنَّ الْمُسْتَشَارَ مُؤْتَمَنٌ، خُذْ هَذَا، فَإِنِّي رَأَيْتُهُ يُصَلِّي، وَاسْتَوْصِ بِهِ خَيْرًا، فَقَالَتِ امْرَأَتُهُ: مَا أَنْتَ بِبَالِغٍ مَا قَالَ فِيهِ النَّبِيُّ ﷺ إِلاَّ أَنْ تُعْتِقَهُ، قَالَ: فَهُوَ عَتِيقٌ، فَقَالَ النَّبِيُّ ﷺ: إِنَّ اللَّهَ لَمْ يَبْعَثْ نَبِيًّا وَلاَ خَلِيفَةً، إِلاَّ وَلَهُ بِطَانَتَانِ: بِطَانَةٌ تَأْمُرُهُ بِالْمَعْرُوفِ وَتَنْهَاهُ عَنِ الْمُنْكَرِ، وَبِطَانَةٌ لاَ تَأْلُوهُ خَبَالاً، وَمَنْ يُوقَ بِطَانَةَ السُّوءِ فَقَدْ وُقِيَ.
