[Machine] Ka'b ibn Malik, when Allah revealed in poetry that which He revealed, came to the Prophet ﷺ and said, "Indeed, Allah, the Most Blessed and Exalted, has revealed in poetry what you know. And what do you think about it?" The Prophet ﷺ said, "Indeed, the believer fights with his sword and his tongue."
أَنَّ كَعْبَ بْنَ مَالِكٍ حِينَ أَنْزَلَ اللهُ تَبَارَكَ وَتَعَالَى فِي الشِّعْرِ مَا أَنْزَلَ أَتَى النَّبِيَّ ﷺ فَقَالَ إِنَّ اللهَ تَبَارَكَ وَتَعَالَى قَدْ أَنْزَلَ فِي الشِّعْرِ مَا قَدْ عَلِمْتَ وَكَيْفَ تَرَى فِيهِ؟ فَقَالَ النَّبِيُّ ﷺ إِنَّ الْمُؤْمِنَ يُجَاهِدُ بِسَيْفِهِ وَلِسَانِهِ
