ahmad:19661And Qāl

[Machine] And the Messenger of Allah ﷺ said, "The heart is named so because of its constant fluctuation. The example of the heart is like a feather suspended in the root of a tree being turned over by the wind, sometimes showing its top and sometimes its bottom."  

أحمد:١٩٦٦١قَالَ

وَقَالَ رَسُولُ اللهِ ﷺ إِنَّمَا سُمِّيَ الْقَلْبُ مِنْ تَقَلُّبِهِ إِنَّمَا مَثَلُ الْقَلْبِ كَمَثَلِ رِيشَةٍ مُعَلَّقَةٍ فِي أَصْلِ شَجَرَةٍ تُقَلِّبُهَا الرِّيحُ ظَهْرًا لِبَطْنٍ
