The Prophet ﷺ as saying: Walk quickly with a funeral, for if the dead person was good it is a good condition to which you are sending him on, but it he was otherwise it is an evil of which you are riding yourselves.  

النَّبِيَّ ﷺ قَالَ أَسْرِعُوا بِالْجَنَازَةِ فَإِنْ تَكُ صَالِحَةً فَخَيْرٌ تُقَدِّمُونَهَا إِلَيْهِ وَإِنْ تَكُ سِوَى ذَلِكَ فَشَرٌّ تَضَعُونَهُ عَنْ رِقَابِكُمْ  

We were walking slowly. AbuBakrah then joined us and he raised his flog at us and said: You have seen us when we were with the Messenger of Allah ﷺ. We were walking quickly.  

لَقَدْ رَأَيْتُنَا وَنَحْنُ مَعَ رَسُولِ اللَّهِ ﷺ نَرْمُلُ رَمَلاً  

We attended the funeral of AbdurRahman ibn Samurah and he said: He (AbuBakrah) made his mule run quickly and pointed with the flog.  

وَقَالَ فَحَمَلَ عَلَيْهِمْ بَغْلَتَهُ وَأَهْوَى بِالسَّوْطِ  

We asked the Prophet ﷺ about walking with the funeral. He replied: Not running (but walking quickly). If he (the dead person) was good, send him to it quickly; if he was otherwise, keep away the people of Hell. The bier should be followed and should not follow. Those who go in front of it are not accompanying it. Abu Dawud said: The narrator Yahya b. 'Abd Allah is weak. He is Yahya al-Jabir Abu Dawud said: This is from Kufah, and Abu Majidah is from Basrah. Abu Dawud said: Abu Majidah is obscure.  

سَأَلْنَا نَبِيَّنَا ﷺ عَنِ الْمَشْىِ مَعَ الْجَنَازَةِ فَقَالَ مَا دُونَ الْخَبَبِ إِنْ يَكُنْ خَيْرًا تَعَجَّلْ إِلَيْهِ وَإِنْ يَكُنْ غَيْرَ ذَلِكَ فَبُعْدًا لأَهْلِ النَّارِ وَالْجَنَازَةُ مَتْبُوعَةٌ وَلاَ تُتْبَعُ لَيْسَ مَعَهَا مَنْ تَقَدَّمَهَا
