Malik related to me from Zayd ibn Aslam from his father that Umar ibn al-Khattab came upon Abu Bakr as-Siddiq pulling his tongue. Umar said to him, "Stop, may Allah forgive you!" Abu Bakr replied, "This has brought me to dangerous places."
أَنَّ عُمَرَ بْنَ الْخَطَّابِ دَخَلَ عَلَى أَبِي بَكْرٍ الصِّدِّيقِ وَهُوَ يَجْبِذُ لِسَانَهُ فَقَالَ لَهُ عُمَرُ مَهْ غَفَرَ اللَّهُ لَكَ فَقَالَ أَبُو بَكْرٍ إِنَّ هَذَا أَوْرَدَنِي الْمَوَارِدَ
