Assalamualaikum. Ahsanallahu ilaykum, shaykh. May Allah grant you goodness. We love you so much for the sake of Allah 🥺🤍 May I kindly ask, when the time for last third of the night starts, does it last until right before fajr? Is it still tahajjud even few minutes before fajr? Jazakallah khairan

If you measure the time between Maghrib and Fajr and divide it into three parts, the third part is the last third. And yes, before the Adhan (by some minutes) is considered part of Tahajjud. May Allah SWT reward you for the beautiful and kind words. Ahabakumullah al-ladhi ahbabtumuna bih (May He, for whose sake you love me, love you).
