On the Night of Al-Isra (the Night of Ascension) the Prophet (ﷺ) was presented with two drinking vessels: one full of wine and the other one full of milk. He looked at them. Then he took the vessel which was full of milk. Thereupon Jibril (Gabriel) said: "Al-hamdu lillah (praise be to Allah) Who has guided you to that, which is in accord with Fitrah (i.e., Islamic Monotheism; pure nature of Islam). Had you selected wine, your people would have gone astray."
