يَتَقَارَبُ الزَّمَانُ، وَيُقْبَضُ الْعِلْمُ، وَتَظْهَرُ الْفِتَنُ، وَيُلْقَى الشُّحُّ، وَيَكْثُرُ الْهَرْجُ، قَالُوا: وَمَا الْهَرْجُ؟ قَالَ: الْقَتْلُ
Translation: Time will draw close, knowledge will be taken away, trials will appear, avaricious miserliness will spread, and harj will increase. They asked, “What is harj?” He replied, “Killing.”

يَتَقَارَبُ الزَّمَانُ describes time drawing close or seeming compressed. يُقْبَضُ الْعِلْمُ refers to knowledge being taken away. الْفِتَنُ means trials or turmoil, and الشُّحُّ combines intense greed with miserliness.
The companions asked the meaning of الْهَرْجُ, and the answer was الْقَتْلُ, killing. Asking for a difficult term to be explained is a model for careful learning.
