Malik related to me from Abd ar-Rahman ibn Abd ar-Rahman ibn Sasaca from his father that Abu Said al-Khudri said that the Messenger of Allah ﷺ said, "It will soon happen that the best property of a muslim will be sheep which he takes to the peaks of the mountains and the valleys, fleeing with his deen from trials."

أَنَّهُ قَالَ قَالَ رَسُولُ اللَّهِ ﷺ يُوشِكُ أَنْ يَكُونَ خَيْرُ مَالِ الْمُسْلِمِ غَنَمًا يَتْبَعُ بِهَا شَعَفَ الْجِبَالِ وَمَوَاقِعَ الْقَطْرِ يَفِرُّ بِدِينِهِ مِنَ الْفِتَنِ
