It was narrated that Jabir bin 'Abdullah said:
"When the Messenger of Allah ﷺ delivered a sermon, his eyes would turn red, he would raise his voice and he would speak with intensity, as if he were warning of an (enemy) army, saying, 'They will surely attack you in the morning, or they will surely attack you in the evening!' He would say: 'I and the Hour have been sent like these two,' and he would hold his index and middle finger. Then he would say: 'The best of guidance is the guidance of Muhammad. The most evil matters are those that are newly-invented, and every innovation (Bid'ah) is a going astray.' And he used to say: 'Whoever dies and leaves behind some wealth, it is for his family, and whoever leaves behind a debt or dependent children, then they are both my responsibility.'"

حَدَّثَنَا سُوَيْدُ بْنُ سَعِيدٍ، وَأَحْمَدُ بْنُ ثَابِتٍ الْجَحْدَرِيُّ، قَالاَ حَدَّثَنَا عَبْدُ الْوَهَّابِ الثَّقَفِيُّ، عَنْ جَعْفَرِ بْنِ مُحَمَّدٍ، عَنْ أَبِيهِ، عَنْ جَابِرِ بْنِ عَبْدِ اللَّهِ، قَالَ كَانَ رَسُولُ اللَّهِ ـ ﷺ ـ إِذَا خَطَبَ احْمَرَّتْ عَيْنَاهُ وَعَلاَ صَوْتُهُ وَاشْتَدَّ غَضَبُهُ كَأَنَّهُ مُنْذِرُ جَيْشٍ يَقُولُ " صَبَّحَكُمْ مَسَّاكُمْ " . وَيَقُولُ " بُعِثْتُ أَنَا وَالسَّاعَةَ كَهَاتَيْنِ " . وَيَقْرِنُ بَيْنَ إِصْبَعَيْهِ السَّبَّابَةِ وَالْوُسْطَى ثُمَّ يَقُولُ " أَمَّا بَعْدُ فَإِنَّ خَيْرَ الأُمُورِ كِتَابُ اللَّهِ وَخَيْرَ الْهَدْىِ هَدْىُ مُحَمَّدٍ وَشَرَّ الأُمُورِ مُحْدَثَاتُهَا وَكُلَّ بِدْعَةٍ ضَلاَلَةٌ " . وَكَانَ يَقُولُ " مَنْ تَرَكَ مَالاً فَلأَهْلِهِ وَمَنْ تَرَكَ دَيْنًا أَوْ ضَيَاعًا فَعَلَىَّ وَإِلَىَّ " .
