What kind of day is it today?
Al Khaleel ibn Ahmad (may Allah have mercy on him) said
أَيََّامِي أَرْبَعَةٌ
I have four kinds of days
يَوْمٌ أَخْرُجُ فَأَلْقَى فِيهِ مَنْ هُوَ أَعْلَمُ مَنِّي
A day when I go out and meet someone more knowledgeable than me
فَأَتَعَلَّمُ مَنْهُ فَذَاكَ يَوْمُ فَائِدَتِي وَ غَنِيمَتِي
so I learn from him, and that is the day of my benefit and profit
وَ يَوْمٌ أَخْرُجُ فَأَلْقَى فِيهِ مَنْ أَنَا أَعْلَمُ مِنْهُ
And a day when I go out and meet someone less knowledgeable than me
فَأُعَلِّمَهُ فَذَاكَ يَوْمُ أَجْرِي
so I teach him, and that is my day of reward
وَ يَوْمٌ أَخْرُجُ فَأَلْقَى فِيهِ مَنْ هُوَ مِثْلِي
And a day when I go out and meet someone like myself
فَأَُذَاكِرُهُ فَذَاكَ يَوْمُ دَرْسِي
so I study and review with him, and that is the day of my lesson
وَ يَوْمٌ أَخْرُجُ فَأَلْقَى فِيهِ مَنْ هُوَ دُونِي وَ هُوَ يَرَى أَنَّهُ فَوْقِي
And a day when I go out and meet someone below my level, but he feels that he is above my level
فَNotَ أكلمه، وَ أَجْعَلْنَا يَوْمَ رَاحَتِي
so I do not talk to him, and I make that my day to relax
