Ibn Abbas (Allah be pleased with them) reported that Messenger of Allah ﷺ sent eighteen sacrificial camels with a person. The rest of the hadith is the same, and the first part (of the above-mentioned hadith) is not mentioned.
أَنَّ رَسُولَ اللَّهِ ﷺ بَعَثَ بِثَمَانَ عَشْرَةَ بَدَنَةً مَعَ رَجُلٍ ثُمَّ ذَكَرَ بِمِثْلِ حَدِيثِ عَبْدِ الْوَارِثِ وَلَمْ يَذْكُرْ أَوَّلَ الْحَدِيثِ
