According to Tafsir al Mizan regarding surah 13:7
"Ibn Shahrashoob narrated it from al-Hakim in Shawahidul Tanzeel, and al-Mirzabani in his book 'What was revealed about the Commander of the Faithful in the Qur'an.'Abdullah ibn Ahmad narrated in Zawaidul Masnad, and ibn abi Hatem al-Tabrani in al-Awsat and al-Hakim, and it was authenticated by ibn Mardawayh and Ibn Asakir from 'Ali ibn abi Talib, regarding Allah, the Exalted's words: 'surely you are a warner and for every people there is a guide'. He said: 'The Messenger of Allah is the warner and I am the guide' and in another expression: 'the guide is a man from Banu Hashim - meaning himself'. (ad-Durru'l-manthur)"
In Mustadrak al-Hakim, with his chain from Ibrahim ibn al-Hakam ibn Dhaheer from his father, from al-Hakam ibn Jareer from Ibn Burayda al-Aslami, he said: “The Messenger of Allah (s.a.w.) called for purity while Ali ibn abi Talib was with him. Then the Messenger of Allah (s.a.w.) took Ali's hand after he had purified (himself) and held it firmly against his chest then said: 'surely you are a warner' and he meant himself, then he returned it to 'Ali's chest and said: 'and for every nation there is a guide'. Then he said to him: 'You are the light of the people, the peak of guidance, the ruler of the reciters. I bear witness that you are so'”
Ibn Jareer, Ibn Mardawayh, Abu Na'eem in al-Ma'rifah and al-Daylami and Ibn Asakir and Ibn Najjar narrated that: “when the verse: 'you are a warner and for every nation there is a guide' was revealed the Messenger of Allah (s.a.w.) placed his hand on his chest and said: 'I am the warner' then he pointed with his hands to the shoulder of 'Ali (a.s) and said: 'you are the guide O Ali, by you the guided ones are guided after me'” (ad-Durru'l-manthur)
