Lesson from Surah Kahf: A rejection, a loss, a delay isn't always a deprivation, it is indeed Allah’s divine help to protect you, give you better and reward you. Alhamdulillah.
Tahajjud brings unimaginable peace and calmness to your heart. There is no noise from the world to distract you, no commitments that call you. It is just you and Allah in the still of the night. Try and pray Tahajjud in the last third of the night and ask Him for whatever u want.
