Jami` at-Tirmidhi: Book 47, Hadith 420

Abu Hurairah narrated that the Messenger of Allah said: “When Allah created Adam, He breathed the soul into him, then he sneezed and said: ‘All praise is due to Allah.’ So he praised Allah by His permission. Then His Lord said to him: ‘May Allah have mercy upon you O Adam. Go to those angels – to that gathering of them sitting – so say: ‘As-Salamu alaikum.’ They said ‘Wa Alaikas-Salamu Wa Rahmatullah’. Then he returned to his Lord, He said: ‘This is your greeting and the greeting of your children among each other.’ Then Allah said to him – while His Two Hands were closed – ‘Choose which of them you wish.’ He said: ‘I chose the right My Lord and both of the Hands of my Lord are right, blessed.’ Then He extended it, and there was Adam and his offspring in it.’ So he said: ‘What are these O my Lord?’ He said: ‘These are your offspring?’ Each one of them had his age written between his eyes. But among them there was a man who was the most illuminating of them – or among the most illuminated of them. He said: ‘O Lord! Who is this?’ He said: ‘This is your son Dawud, I wrote forty years for him.’ He said: ‘O Lord! Add to his age.’ He said: ‘That is what I have written for him.’ He said: ‘O Lord! Give him sixty of my years.’ He said: ‘So you shall have it.’” He said: “Then, he resided in Paradise as long as Allah willed, then he was cast from it, so Adam was counting for himself.” He said: “So the Angel of death came to him, and Adam said to him: ‘You are hasty, one-thousand years were written for me.’ He said: ‘Of course! But you gave sixty years to your son Dawud.’ So he rejected, and his offspring rejected, and he forgot, and his offspring forgot.” He said: “So ever since that day, what is written and witnessed has been decreed.”
