اَلَاۤ اِنَّ اَوْلِیَآءَ اللّٰہِ لَا خَوْفٌ عَلَیْہِمْ وَ لَا  ھُمْ  یَحْزَنُوْنَ (ۚ۶۲) الَّذِیْنَ  اٰمَنُوْا  وَ کَانُوْا  یَتَّقُوْنَ (ؕ۶۳)  لَہُمُ الْبُشْرٰی فِی الْحَیٰوۃِ الدُّنْیَا وَ فِی الْاٰخِرَۃِ ؕ لَا  تَبْدِیْلَ  لِکَلِمٰتِ اللّٰہِ ؕ ذٰلِکَ  ھُوَ  الْفَوْزُ  الْعَظِیْمُ (ؕ۶۴)

Pay heed: the friends of Allah will neither have fear nor will they grieve. Those who embraced faith and adopted piety. There are glad tidings for them in the life of this world and in the Hereafter, there is no changing the Words of Allah, this is supreme success.^[1]

Explaining this verse, Mufti Aḥmad Yār Khān Naʿīmī رَحْمَةُ الـلّٰـهِ عَـلَيْه writes:

O people, listen attentively! Be aware! There is no doubt that the friends of Allah Almighty, those who have attained the good fortune of His closeness; they are not overpowered by the fear, awe, or terror of any creation in this world, because their hearts are filled with the fear of Allah Almighty.

They are free from grief in this world and the Hereafter, as Allah Almighty protects them from both these afflictions. They are sincere, firm believers, constantly pious and Allah-fearing. They do not neglect any farḍ, wājib, or Sunna act, nor do they commit any forbidden deeds. For them, there are glad tidings in this world and the Hereafter.

Testimony of their sainthood is present on the tongues of people. Hearts are inclined towards them. At the time of death, angels give them the glad tidings of Paradise. On the Day of Judgement, they will be given this good news.

These are the promises of Allah Almighty, which never change.O people, this is the great success; aspire towards it!.^[2]
