Ka'b b. Malik reported on the authority of his father that the similitude of a believer is that of a standing crop. The wind sometimes shakes it and sometimes raises it up and then it comes to its destined end. And the similitude of a hypocrite is that of a cypress tree which is not affected by anything but is uprooted once for all.  

قَالَ رَسُولُ اللَّهِ ﷺ مَثَلُ الْمُؤْمِنِ كَمَثَلِ الْخَامَةِ مِنَ الزَّرْعِ تُفِيئُهَا الرِّيَاحُ تَصْرَعُهَا مَرَّةً وَتَعْدِلُهَا حَتَّى يَأْتِيَهُ أَجَلُهُ وَمَثَلُ الْمُنَافِقِ مَثَلُ الأَرْزَةِ الْمُجْذِيَةِ الَّتِي لاَ يُصِيبُهَا شَىْءٌ حَتَّى يَكُونَ انْجِعَافُهَا مَرَّةً وَاحِدَةً  

"مَثَلُ الْمُؤمِن كَالْخَامة (*) مِن الزَّرع، تُفَيِّئهَا الرَّيحُ مرَّةً، وتَعْدلُهَا أُخْري (* *) ومثَلُ الْمُنَافِقِ، كالأرْزَةِ لَا تَزَالُ حَتَّى يكُونَ انْجعَافُهَا مَرَّةً واحِدةً".
