اَلَاۤ اِنَّ اَوْلِیَآءَ اللّٰهِ لَا خَوْفٌ عَلَیْهِمْ وَ لَا هُمْ یَحْزَنُوْنَۚۖ(۶۲)(سورۃ یونس)
Translation
Unquestionably, for the allies of Allah there will be no fear concerning them, nor will they grieve. (62) (Asan Tarjuma Quran)
That is, the explanation of the "allies of Allah" has been given in the next verse: that these are the people who possess the qualities of faith (Iman) and righteousness (Taqwa). Regarding them, it is stated that they will have no fear of the future, nor any grief over the past. Apparently, this is a brief statement, but if looked at closely, it is such a magnificent blessing that its concept cannot even be imagined in this world. This is because every human being in this world, no matter how prosperous they may be, is constantly troubled by some fear of the future or some grief of the past. This blessing will only be achieved in Paradise, where man will become entirely free from every kind of fear and trauma. (Asan Tarjuma Quran)
