The dar al-ifta of Egypt  mentions:
For the throwing of the Jamra’s on the days of Tashreeq: Amongst the ‘ulama with regards to its beginning of its time are three opinions
The first opinion: Is the opinion of the Jumhur ; That the throwing on all the days of Tashreeq is not permitted except after midday; They deduced from the action of the Prophet, Salutations of Allah, and Peace upon him, as per the Hadith of Jabir Bin Abdullah, may Allah be pleased with them both, narrated by Muslim and others – and by Bukhari as an annotation – that the Prophet, Salutations of Allah and Peace be upon him, throw the Jamra on the day of Nahr at the time of Dhuha, and as for the throwing after that, he did so after the sun crosses the meridian.
The second opinion: is that the throwing is permitted before midday on the day of Nafr (day of final exit from Mina); And this is narrated from Ibn Abbas, May Allah be pleased with them both, and the opinion of ‘Ikrama, Ishaq Bin Rahawayh, and the mash-hur view of Abi Hanifa. It is also a narration from Ahmad, and the opinion of some of the Hanbalites except that he place a condition that they do not leave Mina (nafr) except after midday.And in a narration from Abi Hanifa which is agreed upon by Abu Yusuf, may Allah Most High have mercy on them both, it is permissible to throw before zawal on the first Day of Nafr if he intends for ta’ajjul (nafr awal, exit on second day of tashreeq)
The third opinion: That is is permissible for the pilgrim to throw before zawal on all days of Tashreeq, and this is the mazhab of groups of ‘ulamas from the salaf and the khalaf. Amongst them are Abdullah Bin Umar and ‘Abdullah Bin Zubair, may Allah be pleased with them. And Towoos bin Kaisan, ‘Atho bin Abi Rabah in one of two narrations from him and al-Imam Abu Ja’far Muhammad al-Baqir, and this is a narration from Abi Hanifa. al-Taqi as-Subki mentions that this is ma’roof and raajih from the mazhab of ash-shafi’ie. And this is the opinion of al-izz ibn Jama’ah and al-Jamal al-Isnawi as narrated by Imam al-Haramayn in his “Nihaya al-Matlab” ( 4/323, Dar al-Mihaj’s Edition) from the Imams. And ar-Ruyani cited it in “bahr al-Mazhab” (5/217, Dar Ihya al-Turath al-‘Arabi’s Edition) from some of the Khurasan shafiites. And this is the preferred opinion of the hujjatul-Islam al-Ghazali, al-Foorani, al-‘Imrani, ar-Rafi’ie and others from the shafiites. And this is a narration from al-Imam Ahmad. This is the opinion of a group from the hanbalites such as Abi al-Wafa’ bin ‘Aqil, Abi al-Farj bin al-Jawzi, Abi al-Hasan Bin al-Zaghuni, and others. Ibn Muflih al-Hanbali said in al-Faroo’ (6/59, Muassasa al-Risalah’s edition): “Ibn al-Jazwi considers it permissible before midday, and in al-Wadhih : and the rising of the sun (dawn), except on the third day. And he did not restrict it as well in his “Manasik” to throw it in the earliest of its time, and that he throws on the third day as per the two days before it, and then he makes nafr (final exit from Mina)” and Ibn Rajab al-Hanbali cited in “al-Zhil ‘alaa Tobaqot al-Hanabila” (1/408, Maktaba al-‘Abikan’s edition) from Ibn al-Zaghuni in his “Manasik” that the throwing of the Jamrah’s on the days of Mina, and the throwing of the Jamra al-‘Aqaba on the day of Nahr is permitted before mid-day but the most afdhal is after mid-day.
