Allah the Exalted said:
وَاتَّقُوا يَوْمًا تُرْجَعُونَ فِيهِ إِلَى اللهِ ثُمَّ تُوَفَّى كُلُّ نَفْسٍ مَا كَسَبَتْ وَهُمْ لا يُظْلَمُونَ
This Ayah means: “And fear a day in which you will be resurrected and judged by Allah. Then, based on one’s deeds in this life, one will be either rewarded or punished and they will never be wronged.”
Fear Allah and never waste your time in acts of disobedience to Allah. For indeed the successful one is the one who does not engage in worldly pleasures throughout his life, rather, he enlightens his grave with righteous deeds before he will be admitted into it.
