Is stoning the Jamarat on the days of Tashreeq valid before zawal due to overcrowding, especially on the twelfth day?

Scholars differed on the time for stoning Jamrat al-Aqaba on the Day of Sacrifice and the three Jamarat during the Days of Tashreeq for three reasons: varying texts, recognized considerations such as crowding and hastening, and the timing within days and nights.

Stoning Jamrat al-Aqaba: The preferred time is from after sunrise on the Day of Sacrifice until sunset. It is permissible after dawn, and for those with excuses, stoning before dawn is allowed.

Stoning the Jamarat during the Days of Tashreeq: It begins after the sun's zenith according to the majority of scholars, due to the Prophet's (peace be upon him) action. The preferred time ends at sunset, and the permissible time extends until just before the dawn of the following day. Concession for stoning at night is stronger than concession for stoning before the sun's zenith.
