Narrated Ali ibn AbuTalib: AbuDawud said: Al-Hasan ibn Ali traced this tradition back to the Prophet (ﷺ): When people are passing by, it is enough if one of them gives a salutation on their behalf, and that it is enough for those who are sitting if one of them replies.

حَدَّثَنَا الْحَسَنُ بْنُ عَلِيٍّ، حَدَّثَنَا عَبْدُ الْمَلِكِ بْنُ إِبْرَاهِيمَ الْجُدِّيُّ، حَدَّثَنَا سَعِيدُ بْنُ خَالِدٍ الْخُزَاعِيُّ، قَالَ حَدَّثَنِي عَبْدُ اللَّهِ بْنُ الْمُفَضَّلِ، حَدَّثَنَا عُبَيْدُ اللَّهِ بْنُ أَبِي رَافِعٍ، عَنْ عَلِيِّ بْنِ أَبِي طَالِبٍ، رضى الله عنه - قَالَ أَبُو دَاوُدَ رَفَعَهُ الْحَسَنُ بْنُ عَلِيٍّ - قَالَ ‏ "‏ يُجْزِئُ عَنِ الْجَمَاعَةِ، إِذَا مَرُّوا أَنْ يُسَلِّمَ، أَحَدُهُمْ وَيُجْزِئُ عَنِ الْجُلُوسِ أَنْ يَرُدَّ أَحَدُهُمْ ‏"‏ ‏.‏
