Mishkat al-Masabih — Hadith #37484

Abu Huraira reported God’s messenger as saying, “When God created Adam He wiped his back and every soul of his offspring He was to create up to the day of resurrection fell from his back. He put on the forehead of everyone of them a flash of light, then presented them to Adam who asked, ‘My Lord, who are these?’ He replied, ‘Your offspring.' On seeing one of them and being charmed by the flash on his forehead he asked, ‘My Lord, who is this?’ He replied, ‘David.’ He asked, ‘My Lord, how long a term of life hast Thou appointed him?” He replied, ‘Sixty years.’ He said, ‘My Lord, give him an extra forty years out of my term of life.’” God’s messenger said, “When Adam’s period of life all but forty years had come to an end the angel of death came to him. Adam said, ‘Are there not forty years of my life remaining?’ He replied, ‘Did you not give them to your son David?' Adam denied it and his offspring denied; Adam forgot and ate of the tree and his offspring forgot; and Adam sinned and his offspring sinned.” Tirmidhi transmitted it.
