(Ahqaaf) 46 : 13
إِنَّ الَّذِينَ قَالُوا رَبُّنَا اللَّهُ ثُمَّ اسْتَقَامُوا فَلَا خَوْفٌ عَلَيْهِمْ وَلَا هُمْ يَحْزَنُونَ
Indeed those who declare that Our Lord is Allah, then steadfast in it, there shall be no fear upon them, and for them won’t be grieved.
The one in thousand believer who testifies Adhikr will return to the Paradise. As explained in verse 2: 62, if the other people belonging to Messenger’s community are doing righteous deeds believing in Lord of the universe and on the Day of Judgement, there shall be no fear upon them, and for them won’t be grieved. See explanation 7: 35, 205-206; and 41: 30.
