The Messenger of Allah ﷺ as saying: The time will become short, knowledge will be decreased, civil strife (fitan) will appear, niggardliness will be case into people's heart, and harj will be prevalent. He was asked: Messenger of Allah! what is it: He replied: Slaughter, slaughter. (Using translation from Abū Dāʾūd 4255)
قَالَ رَسُولُ اللهِ ﷺ يَتَقَارَبُ الزَّمَانُ وَيَفِيضُ الْمَالُ وَتَظْهَرُ الْفِتَنُ وَيَكْثُرُ الْهَرْجُ قَالُوا وَمَا الْهَرْجُ يَا رَسُولَ اللهِ؟ قَالَ الْقَتْلُ الْقَتْلُ
