Sahih Bukhari | Volume 7 | Hadith Number 482

Narrated by Abu Huraira
On the night Allah's Apostle was taken on a night journey (Miraj) two cups, one containing wine and the other milk, were presented to him at Jerusalem. He looked at it and took the cup of milk. Gabriel said, "Praise be to Allah Who guided you to Al-Fitra (the right path); if you had taken (the cup of) wine, your nation would have gone astray."
