Is it permissible to delay the stoning of Jamrat al-Aqabah until after the 'Isha prayer on the Day of Sacrifice, after performing Tawaf al-Ifadah, Sa'y, and shaving/shortening at dawn?

There is no objection to performing Tawaf, Sa'i, and shaving (or cutting the hair) before stoning Jamrat al-Aqaba. As for stoning Jamrat al-Aqaba after sunset, it is preferable to stone it after the sun passes its zenith on the day of Eid. However, there is no objection to stoning it at night, based on the opinion of some jurists and citing the Hadith of Ibn Abbas in Al-Bukhari: "The Prophet, peace and blessings be upon him, was asked, 'I stoned after evening fell.' He said, 'There is no objection.'"
