"Indeed, those who have believed and done righteous deeds"—meaning: what Allah has obligated upon them—"shall have their reward with their Lord"—meaning: Paradise—"and there shall be no fear upon them, nor shall they grieve" over the worldly life. [Ayah 278-279]
﴿إِنَّ الَّذِينَ آمَنُوا وَعَمِلُوا الصَّالِحَاتِ﴾ يَعْنِي: مَا افْترض اللَّه عَلَيْهِم ﴿لَهُم أجرهم عِنْد رَبهم﴾ يَعْنِي: الْجَنَّة ﴿وَلا خَوْفٌ عَلَيْهِمْ وَلَا هم يَحْزَنُونَ﴾ على الدُّنْيَا. [آيَة ٢٧٨ - ٢٧٩]
