(Al-Jasiya ) 45 : 30
فَأَمَّا الَّذِينَ آمَنُوا وَعَمِلُوا الصَّالِحَاتِ فَيُدْخِلُهُمْ رَبُّهُمْ فِي رَحْمَتِهِ ۚ ذَٰلِكَ هُوَ الْفَوْزُ الْمُبِينُ
Then those who believed and did righteous deeds—their Lord will admit them into His Mercy. That is the Manifest Triumph.
The best deed is to propagate Adhikr—the Permission of Allah to become a believer as explained in verse 10: 100—to the entire mankind. Mercy is one of the forty names of Adhikr. So, for the believer who utilizes Adhikr as the Shield and Safeguard against all calamities, disasters, diseases, and Hellfire, and utilizes It as the Ticket to return to Paradise and conveys It to other people for the same, Adhikr will argue and witness in favor of him, will intercede for him, and make him intercede for others. See explanation 35: 32; 43: 86; and 45: 13.
