Volumn 001, Book 012, Hadith Number 715.
Narated By ‘Abdullah bin ‘Abbas : Once solar eclipse occurred during the lifetime of Allah’s Apostle. He offered the eclipse prayer. His companions asked, “O Allah’s Apostle! We saw you trying to take something while standing at your place and then we saw you retreating.” The Prophet said, “I was shown Paradise and wanted to have a bunch of fruit from it. Had I taken it, you would have eaten from it as long as the world remains.”
