(Al-Muzammil) 73 : 19
إِنَّ هَٰذِهِ تَذْكِرَةٌ ۖ فَمَنْ شَاءَ اتَّخَذَ إِلَىٰ رَبِّهِ سَبِيلًا

Indeed this is the Ticket to the one who seeks Path to His Lord.

This verse is repeated in verse 76: 29. Adhikr is the Ticket to reach to Allah who is in the Paradise. That means without utilising Adhikr-the Ticket, none can enter to the Paradise. If it is told in verse 69: 48 that one in thousand believer to the Paradise who are Heedful will only utilise Adhikr as the Ticket to the Paradise, it is told in verse 69: 50 that Adhikr is a cause of sorrow for the disbelievers. It is told in verse 80: 17 that the human who hid Adhikr has been killed; and in verse 63: 4 it is told that Allah has killed the Hypocrites. See explanation 9: 67-68, 84-85; 18: 100-101.
