It is narrated from Hazrat Buraidah (may Allah be pleased with him) that I heard the Holy Prophet (peace and blessings be upon him) say: There are five things which none but Allah knows: The knowledge of the Hour is with Allah alone; He alone sends down the rain; He alone knows what is in the womb (whether fortunate or unfortunate); no person knows what he will earn tomorrow; and no person knows in which land he will die. Surely, Allah is All-Knowing and All-Aware of everything.
