﴿ وَٱذْكُر رَّبَّكَ فِى نَفْسِكَ تَضَرُّعًۭا وَخِيفَةًۭ وَدُونَ ٱلْجَهْرِ مِنَ ٱلْقَوْلِ بِٱلْغُدُوِّ وَٱلْءَاصَالِ وَلَا تَكُن مِّنَ ٱلْغَٰفِلِينَ ﴾

“And bethink thyself of thy Sustainer humbly and with awe, and without raising thy voice, at morn and at evening; and do not allow thyself to be heedless.”

And remember thy Lord in thyself. The rememberers are three men: One remembers with the tongue while the heart is unaware. Another remembers with both tongue and heart, but his work is in danger, as has been said, " The self-purifiers are in grave danger. " Still another is silent with the tongue but his heart is drowned in Him. The Pir of the Tariqah said, " O God, how can I remember, for I myself am all remembrance? I have given the harvest of my marks to the wind. How can I remember Him whom I have not for- gotten? O remembrance of the spirits, remembered by the hearts, and mentioned by the tongues! Remember me with Your bounty and make me happy with gentle remembrance! "
