(Al-Muzammil) 73 : 8
وَاذْكُرِ اسْمَ رَبِّكَ وَتَبَتَّلْ إِلَيْهِ تَبْتِيلًا
And you remember the name of your Lord, and you do preparation to return to Him.
This verse commands the believer that since Adhikr is codified as a Book, he should live here under the Light of It remembering the Lord always, and should codify the life under the Light of Adhikr, and should prepare Paradise in this fourth phase in order to get it in the seventh phase in the Hereafter as explained in verse 7: 43. See explanation 50: 31-35; 70: 19; and 76: 25-26.
