Q.What is the time of performing Tahajjud Salaah? Can I perform Tahajjud Salaah at Fajr time?
(Question published as received)
A. Tahajjud Salaah may be performed after the Esha Salaah until Subah Saadiq (the starting of Fajr Salaah time).However, the reward for Tahajjud Salaah increases if it is performed after half of the night has elapsed.
Tahajjud Salaah cannot be performed after Subah Saadiq or at Fajr Salaah time.
Allah Knows Best
