Allah Almighty says in the Sura of AL-MUZZAMMIL: {Indeed, the first part of night is heavier in tread and more upright in speech}.1 the firmest and most steadfast step is the step taken by the servant in the middle of night while everyone is asleep, he wakes up so as to be alone with Allah, he stands to say prayers and recites the Holy Quran plaintively.in the privacy of the night the heart is devoid of all dialy activities and works. So, far from the eyes of strangers and outsiders he speaks with his confidant, he (both) gives and takes love, plays hard and then, repeats begging love
