Imam Tirmidhi says:
1- This hadith is Hasan Gharib.
2- I asked Muhammad bin Isma'il al-Bukhari about this hadith, and he said: This hadith of Abdul Aziz is of the category of Mukhtalif, and it is only known through his narration.
3- In this chapter, hadiths have also been narrated from Jabir, Ka'b bin Malik, and Anas (may Allah be pleased with them). We know it from this chain only through the narration of Suhail.
