The Messenger of Allah ﷺ as saying: A Muslim's best property will soon be sheep which he will take to the tops of the mountains and the places where the rain falls, fleeing with his religion from the civil strife (fitan). (Using translation from Abū Dāʾūd 4267)
قَالَ رَسُولُ اللهِ ﷺ يُوشِكُ أَنْ يَكُونَ خَيْرَ مَالِ الْمَرْءِ الْمُسْلِمِ غَنَمٌ يَتْبَعُ بِهَا شَعَفَ الْجِبَالِ وَمَوَاقِعَ الْقَطْرِ يَفِرُّ بِدِينِهِ مِنَ الْفِتَنِ
