Grading: Its chain is weak.
Technical note / Defect ('illah): Muhammad bin Ishaq (Ibn Yasar) is a mudallis, and here he narrated with 'an'anah and did not state that he heard it directly.

Reference / Source: It was recorded by al-Bayhaqi in "al-Sunan al-Kubra" 5/177 from Abu 'Abdullah al-Hakim, with this chain.

Reference / Source: It was recorded by al-Azraqi in "Akhbar Makkah" 1/72-73 via 'Uthman bin Saj, from Muhammad bin Ishaq, who said: "Someone whom I do not suspect narrated to me" (i.e. an unnamed person), from Ibn 'Abbas.

Details of the narration: Its second part alone was recorded by al-Fakihi in "Akhbar Makkah" (2593), al-Tabarani in "al-Awsat" (5407) and "al-Kabir" (12283), Abu Tahir al-Mukhallis in "al-Mukhallisiyyat" (1286), Ibn 'Asakir in "Tarikh Dimashq" 61/167 and al-Diya' al-Maqdisi in "al-Ahadith al-Mukhtarah" 10/(309), via Muhammad bin Fudayl, from 'Ata' bin al-Sa'ib, from Sa'id bin Jubayr, from Ibn 'Abbas, as marfu'.
Technical note / Defect ('illah): However, Muhammad bin Fudayl is among those who heard from 'Ata' bin al-Sa'ib after his memory deteriorated.

Reference / Source: It was recorded by al-Azraqi in "Akhbar Makkah" 1/69 and 2/174, al-Fakihi in "Akhbar Makkah" (2603) and Ibn al-Jawzi in "Muthir al-'Azm al-Sakin ila Ashraf al-Amakin" (189) via Ash'ath bin Sawwar, from 'Ikrimah, from Ibn 'Abbas, as mawquf.
Technical note / Defect ('illah): Ash'ath bin Sawwar is a weak narrator.

Corroborating chains and supporting reports: On this topic there is also a narration from Abu Musa al-Ash'ari, in Yunus bin Bukayr's additions to "Maghazi Ibn Ishaq" (83), Abu Ya'la (7231) and (7271), al-'Uqayli in "al-Du'afa'" (32), Abu Nu'aym in "al-Hilyah" 1/259, Ibn 'Asakir in "Tarikh Dimashq" 32/230 and 61/166, and others, with a very weak chain.

Technical note / Defect ('illah): The majority of scholars declare this Kathir weak.

Corroborating chains and supporting reports: From Abu Hurayrah, mawquf on him, it was recorded by Musaddad in his "Musnad" (as in al-Busiri's "Ithaf al-Khiyarah" (965)). Also al-Bazzar (1177 - Kashf al-Astar), al-Fakihi in "Akhbar Makkah" (2594), Abu Ya'la in "al-Kabir" (as in "al-Matalib al-'Aliyah" (1332)) and al-Tabarani in "al-Kabir" (13525) recorded from the hadith of 'Abdullah bin 'Umar, as marfu': "In Masjid al-Khayf are the graves of seventy prophets."
