The Messenger of Allah ﷺ used to stand up for a funeral until the corpse was placed in the grave. A learned Jew (once) passed him and said: This is how we do. The Prophet ﷺ sat down and said: Sit down and act differently from them.
كَانَ رَسُولُ اللَّهِ ﷺ يَقُومُ فِي الْجَنَازَةِ حَتَّى تُوضَعَ فِي اللَّحْدِ فَمَرَّ بِهِ حَبْرٌ مِنَ الْيَهُودِ فَقَالَ هَكَذَا نَفْعَلُ فَجَلَسَ النَّبِيُّ ﷺ وَقَالَ اجْلِسُوا خَالِفُوهُمْ
“When the Messenger of Allah ﷺ followed a funeral, he would not sit down until it had been placed in the niche-grave. A rabbi came to him and said: ‘This is what we do, O Muhammad!’ So the Messenger of Allah ﷺ sat down and said: ‘Be different from them.’”
كَانَ رَسُولُ اللَّهِ ﷺ إِذَا اتَّبَعَ جِنَازَةً لَمْ يَقْعُدْ حَتَّى تُوضَعَ فِي اللَّحْدِ فَعَرَضَ لَهُ حَبْرٌ فَقَالَ هَكَذَا نَصْنَعُ يَا مُحَمَّدُ فَجَلَسَ رَسُولُ اللَّهِ ﷺ وَقَالَ خَالِفُوهُمْ
"عن عبادة بن الصَّامت قال: كان رسول الله ﷺ إِذا اتّبعَ جِنازَةً لَمْ يَجْلسْ حتَّى تُوضَعَ فِى اللَّحْدِ، فَعَرضَ حَبْرٌ منَ اليَهُودِ فَقَالَ: هَكَذَا نَفْعَلُ، فَجلَسَ رَسُولُ الله ﷺ ، وَقَالَ: خَالفُوهُمْ".
