From Quran, two last verses of Surah(Chapter) 34:
O humanity! Be mindful of your Lord, and beware of a Day when no parent will be of any benefit to their child, nor will a child be of any benefit to their parent. Surely God’s promise is true. So do not let the life of this world deceive you, nor let the Chief Deceiver deceive you about God.
Indeed, God has the knowledge of the Hour. He sends down the rain, and knows what is in the wombs. No soul knows what it will earn for tomorrow, and no soul knows in what land it will die. Surely God is All-Knowing, All-Aware.
