“The seeker is steady in praying the pre-dawn (tahajjud) salah.
(In addition to being a Sunna) It is especially effective in defence against the hell-fire.
It has other benefits, such as subjugating the inner-self (nafs), creating awe (khashiyet) of Allah and bring one closer to the Truth (haq).”

Allah give us the tawfiq. Amin!
