Hadith 30:18
Abu Salama ibn 'Abdu'r-Rahman said, "The Companions of the Messenger of Allah, may Allah bless him and grant him peace, were neither niggardly nor weak (in worship). They used to recite poems to one another in their gatherings and they mentioned matters of the Jahiliyya. But when one of them was asked about something concerning Allah, his eyes went around as if he were mad."
حَدَّثَنَا إِسْحَاقُ، قَالَ: حَدَّثَنَا مُحَمَّدُ بْنُ فُضَيْلِ، قَالَ: حَدَّثَنَا الْوَلِيدُ بْنُ جَمِيعٍ، عَنْ أَبِي سَلَمَةَ بْنِ عَبْدِ الرَّحْمَنِ قَالَ: لَمْ يَكُنْ أَصْحَابُ رَسُولِ اللهِ صلى الله عليه وسلم مُتَحَزِّقِينَ، وَلاَ مُتَمَاوِتِينَ، وَكَانُوا يَتَنَاشَدُونَ الشِّعْرَ فِي مَجَالِسِهِمْ، وَيَذْكُرُونَ أَمْرَ جَاهِلِيَّتِهِمْ، فَإِذَا أُرِيدَ أَحَدٌ مِنْهُمْ عَلَى شَيْءٍ مِنْ أَمْرِ اللهِ، دَارَتْ حَمَالِيقُ عَيْنَيْهِ كَأَنَّهُ مَجْنُونٌ
