One of the disputed ahadeeth is found in Saheeh Muslim under “The Book of Descriptions of Judgment Day, Paradise and Hell”
Chapter “The Beginning of the Creation and the Creation of Adam” alayhis salaam
TRANSLATION: Abu Haraira reported that Rasoolullaah sallAllaahu alayhi wa sallam took hold of my hands and said: “Allaah, the Exalted and Glorious, created the clay on Saturday and He created the mountains on Sunday and He created the trees on Monday and He created the things entailing labor on Tuesday and created light on Wednesday and caused the animals to spread on Thursday and created Adam after ‘Asr on Friday, the last creation at the last hour of the hours of Friday.”
Several other hadeeth scholars collected this report, such as Imaam Ahmed in his Musnad, Imaam ibn Hiban in his ‘Kitab at-Tarikh’.
One scholar disputing its authenticity was Imaam bin Taymia in his ‘Majmua’ al-Fatawa’ who states other hadeeth scholars, such as Imaam Bukhaari from his ‘Tarikh’, saying that this hadeeth is not the words of Rasooullaah sallAllaahu alayhi wa sallam, but rather the words of a Tabi’ named Ka’b al-Ahbar. Imaam bin Taymia also said that some hadeeth scholars, likes of Imaam bin Jauzi, did in fact accept this hadeeth as authentic and attributed to Rasoolullaah sallAllaahu alayhi wa sallam.
Ka’b al-Ahbar was a Jewish rabbi who became Muslim under Ameer ul Mumineen ‘Umar bin al-Khatab’s (ra) rule and died under Ameer ul Mumineen ‘Uthmaan bin ‘Affaans (ra) reign. He was known to have narrated many israilite traditions.
And Allaahs knowledge encompasses all things.
