The Messenger of Allah [SAW] said: "The parable of the hypocrite is that of a sheep that hesitates between two flocks, sometimes following one, and sometimes following another, not knowing which to follow."  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ مَثَلُ الْمُنَافِقِ كَمَثَلِ الشَّاةِ الْعَائِرَةِ بَيْنَ الْغَنَمَيْنِ تَعِيرُ فِي هَذِهِ مَرَّةً وَفِي هَذِهِ مَرَّةً لَا تَدْرِي أَيَّهَا تَتْبَعُ
