Messenger of Allah ﷺ was presented with two cups one containing wine and the other milk on the night of his night journey at Jerusalem. He looked at it and took the milk. Gabriel said, "Thanks to Allah Who guided you to the Fitra (i.e. Islam); if you had taken the wine, your followers would have gone astray. (Using translation from Bukhārī 4709)   

أَنَّهُ سَمِعَ أَبَا هُرَيْرَةَ يَقُولُ أُتِيَ رَسُولُ اللهِ ﷺ لَيْلَةَ أُسْرِيَ بِهِ بِقَدَحَيْنِ مِنْ خَمْرٍ وَلَبَنٍ فَنَظَرَ إِلَيْهِمَا ثُمَّ أَخَذَ اللَّبَنَ فَقَالَ جِبْرِيلُ هُدِيتَ لِلْفِطْرَةِ لَوْ أَخَذْتَ الْخَمْرَ غَوْتَ أُمَّتُكَ
