[Machine] The Messenger of Allah ﷺ heard a man saying the talbiyah on behalf of Shubrumah. So, he called him and asked him, "Have you performed Hajj?" The man replied, "No." The Prophet said to him, "Then this is on your behalf, and perform Hajj for Shubrumah as well." This was narrated from Abdullah ibn Habib ibn Abi Thabit, from Ata, from Ibn Abbas, through a connected chain of transmitters. And the narration of whoever narrates the hadith of Ata as a mursal (chain of narrators missing a link) is more authentic. And Allah knows best.  

سَمِعَ رَسُولُ اللهِ ﷺ رَجُلًا يُلَبِّي عَنْ شُبْرُمَةَ قَالَ فَدَعَاهُ فَقَالَ لَهُ هَلْ حَجَجْتَ؟ قَالَ لَا قَالَ فَهَذِهِ عَنْكَ وَحُجَّ عَنْ شُبْرُمَةَ وَكَذَلِكَ رُوِيَ عَنْ عَبْدِ اللهِ بْنِ حَبِيبِ بْنِ أَبِي ثَابِتٍ عَنْ عَطَاءٍ عَنِ ابْنِ عَبَّاسٍ مُسْنَدًا وَرِوَايَةُ مَنْ رَوَى حَدِيثَ عَطَاءٍ مُرْسَلًا أَصَحُّ وَاللهُ أَعْلَمُ
