V:7 Sura Al-Araf, Ayat 187 –
Narrated ‘Abdullah رضی اللہ عنہ: ALLAH’s Messenger Muhammad صَلَّى اللّٰهُ عَلَيْهِ وَسَلَّم said, “The keys of the unseen are five: Verily ALLAH! With Him (Alone) is the knowledge of the Hour, He sends down the rain, and knows that which is in the wombs. No person knows what he will earn tomorrow, and no person knows in what land he will die. Verily, ALLAH is All-Knower, All-Aware.” (Sahih Al-Bukhari, Vol.6, Hadith No.151).
