Test of life
The Qur’an states:
الَّذِي خَلَقَ الْمَوْتَ وَالْحَيَاةَ لِيَبْلُوَكُمْ أَيُّكُمْ أَحْسَنُ عَمَلًا
“Allah has created death and life to test which one of you is best in conduct.” ―Quran 67:2
يَوْمَئِذٍ تُعْرَضُونَ لَا تَخْفَىٰ مِنكُمْ خَافِيَةٌ
That Day (ie,. Day of judgment) on which you will be brought to judgment, not a secret of yours will be hidden.
— Qur’an 69:18
يَوْمَ تَشْهَدُ عَلَيْهِمْ أَلْسِنَتُهُمْ وَأَيْدِيهِمْ وَأَرْجُلُهُم بِمَا كَانُوا يَعْمَلُونَ
on the Day their tongues, hands, and feet will testify against them for what they used to do.
— Qur’an 24:24
All human beings will be resurrected and brought before the Almighty to be judged. On that day, everyone will stand alone before God.
