Where are the 5 keys of the unseen mentioned in the Quran?

Answer 1

The 5 keys of the unseen that only Allah knows (God in English) are:

1. knowledge of the Hour (the Resurrection day),
2. sends down the rain,
3. knows what is in the wombs,
4. know what you will earn tomorrow, and
5. know in what land you will die

Quran says:

إِنَّ اللَّـهَ عِندَهُ عِلْمُ السَّاعَةِ وَيُنَزِّلُ الْغَيْثَ وَيَعْلَمُ مَا فِي الْأَرْحَامِ ۖ وَمَا تَدْرِي نَفْسٌ مَّاذَا تَكْسِبُ غَدًا ۖ وَمَا تَدْرِي نَفْسٌ بِأَيِّ أَرْضٍ تَمُوتُ ۚ إِنَّ اللَّـهَ عَلِيمٌ خَبِيرٌ ﴿٣٤﴾

Meaning English translation:

{Indeed, Allah [alone] has knowledge of the Hour and sends down the rain and knows what is in the wombs. And no soul perceives what it will earn tomorrow, and no soul perceives in what land it will die. Indeed, Allah is Knowing and Acquainted. (34) } [Quran, chapter 31, Surat Luqman, verse 34]
