On the night Messenger of Allah ﷺ 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." (Using translation from Bukhārī 5576)  

أَنَّهُ سَمِعَ أَبَا هُرَيْرَةَ يَقُولُ أُتِيَ النَّبِيُّ ﷺ لَيْلَةَ أُسْرِيَ بِهِ بِإِيلِيَاءَ بِقَدَحَيْنِ مِنْ خَمْرٍ وَلَبَنٍ فَنَظَرَ إِلَيْهِمَا ثُمَّ أَخَذَ اللَّبَنَ فَقَالَ جِِبْرَائِِيلُ «الْحَمْدُ لِلَّهِ الَّذِي هَدَاكَ لِلْفِطْرَةِ لَوْ أَخَذْتَ الْخَمْرَ غَوَتْ أُمَّتُكَ»
