سَعْدُ بْنُ إِبْرَاهِيمَ، عَنِ ابْنِ كَعْبِ بْنِ مَالِكٍ
Ka'b reported that Messenger of Allah ﷺ said that the similitude of a believer is that of a standing crop in a field which is shaken by wind and then it comes to its original position but it stands at its roots. The similitude of a non-believer is that of a cypress tree which stands on its roots and nothing shakes it but it is uprooted (with) one (violent stroke). (Using translation from Muslim 2810a)
قَالَ رَسُولُ اللهِ ﷺ «مَثَلُ الْمُؤْمِنِ كَمَثَلِ الْخَامَةِ مِنَ الزَّرْعِ تُقَلِّبُهَا الرِّيحُ تَصْرَعُهَا مَرَّةً وَتَعْدِلُهَا أُخْرَى وَمَثَلُ الْكَافِرِ كَمَثَلِ الْأَرْزَةِ الْمُجْذِبَةِ عَلَى أَصْلِهَا لَا يُفَيِّئُهَا شَيْءٌ حَتَّى يَكُونَ انْجِفَافُهَا مَرَّةً وَاحِدَةً»
