How authentic is the Hadith of Addas and the Hadith "Indeed, God will grant victory to your father"?

The story of Addas was narrated by Ibn Ishaq with a mursal (indirect) chain of transmission from Muhammad ibn Ka'b al-Qurazi, and Al-Albani deemed it weak for that reason. Some early scholars mentioned it without a chain of transmission. As for the hadith (definition), "Indeed, Allah is the Helper of your father," it was narrated by Al-Tabari and Ibn Hisham from Ibn Ishaq with a mursal chain of transmission from Urwa ibn al-Zubayr, and Al-Albani also deemed it weak. Al-Bayhaqi and Ibn Asakir narrated it from Ibn Ishaq from a narrator from him, from Urwa, from Abdullah ibn Ja'far, thus removing the mursal element, but Ibn Ishaq's shaykh (teacher) in it is unknown.
