What is the ruling on partaking of the suhoor meal approximately 15 minutes before sunrise, based on the hadith of Aisha (may Allah be pleased with her)?

The time for Suhoor ends with the appearance of the second dawn (al-Fajr al-Sadiq), which is the true dawn that spreads across the horizon. This is the time specified by Islamic law for beginning the fast. The Sunnah is to delay Suhoor until its very last moment, meaning just before the appearance of the second dawn, as the Messenger of Allah, peace and blessings be upon him, used to do. Aisha, may Allah be pleased with her, mentioned that "Three things are from prophethood: hastening to break the fast, delaying Suhoor, and placing the right hand over the left in prayer."
