"I heard the Messenger of Allah ﷺ saying, 'There are two eyes that shall not be touched by the Fire: An eye that wept from the fear of Allah, and an eye that spent the night standing on guard in the cause of Allah."  

سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ عَيْنَانِ لاَ تَمَسُّهُمَا النَّارُ عَيْنٌ بَكَتْ مِنْ خَشْيَةِ اللَّهِ وَعَيْنٌ بَاتَتْ تَحْرُسُ فِي سَبِيلِ اللَّهِ
