What is the authenticity of Hadith number 398, and is it Marfu’ (attributed to the Prophet) or Mawquf (attributed to a Companion), which states: "Indeed, people from my Ummah will come with sins like mountains, and Allah will forgive them and place those sins upon the Jews and Christians"?

This Hadith has a disputed authenticity. Although it was narrated by Muslim, it was weakened by Al-Bayhaqi, Al-Dhahabi, Ibn Hajar, and Al-Albani, who later retracted his authentication of it. Al-Bayhaqi pointed out the weakness of the narrator, Shaddad Abu Talhah, and that he was the only one to narrate it. He also stated that the Hadith contradicts fundamental Islamic principles, such as the verse: "And no bearer of burdens will bear the burden of another." Al-Nawawi and Ibn Hajar interpreted the Hadith metaphorically, meaning that Allah forgives the sins of Muslims and places a similar burden upon Jews and Christians due to their disbelief and sins, or that the disbelievers initiated these sins, and they remain attributed to them.
