[Machine] Al-Shafi'i is not consistent among the knowledgeable scholars regarding his statements about hadith. Most of the scholars I have encountered say that when it comes to camels, they are lean. Based on analogy, we said that camels are lean. However, Sheikh Wajh questioned its authenticity, as it is narrated by someone who is unreliable. Ata' al-Khorasani was born in the year fifty, did not live long enough to witness the eras of Umar, Ali, or Zaid, and he was still a child during Muawiyah's time. It is not established that he heard anything from Ibn Abbas, although it is possible that he may have heard from him, as Ibn Abbas passed away in the year sixty-eight. However, Ata' al-Khorasani's narration has gaps when compared to the narrations of the scholars of hadith. And Allah knows best.  

الشَّافِعِيُّ هَذَا غَيْرُ ثَابِتٍ عِنْدَ أَهْلِ الْعِلْمِ بِالْحَدِيثِ وَهُوَ قَوْلُ الْأَكْثَرِ مِمَّنْ لَقِيتُ فَبِقَوْلِهِمْ إِنَّ فِي النَّعَامَةِ بَدَنَةً وَبِالْقِيَاسِ قُلْنَا فِي النَّعَامَةِ بَدَنَةٌ لَا بِهَذَا قَالَ الشَّيْخُ وَجْهُ ضَعْفِهِ كَوْنُهُ مُرْسَلًا فَإِنَّ عَطَاءً الْخُرَاسَانِيَّ وُلِدَ سَنَةَ خَمْسِينَ وَلَمْ يُدْرِكْ عُمَرَ وَلَا عُثْمَانَ وَلَا عَلِيًّا وَلَا زَيْدًا وَكَانَ فِي زَمَنِ مُعَاوِيَةَ صَبِيًّا وَلَمْ يَثْبُتْ لَهُ سَمَاعٌ مِنَ ابْنِ عَبَّاسٍ وَإنْ كَانَ يُحْتَمَلُ أَنْ يَكُونَ سَمِعَ مِنْهُ فَإِنَّ ابْنَ عَبَّاسٍ تُوُفِّيَ سَنَةَ ثَمَانٍ وَسِتِّينَ إِلَّا أَنَّ عَطَاءً الْخُرَاسَانِيَّ مَعَ انْقِطَاعِ حَدِيثِهِ عَمَّنْ سَمَّيْنَا مِمَّنْ تَكَلَّمَ فِيهِ أَهْلُ الْعِلْمِ بِالْحَدِيثِ وَاللهُ أَعْلَمُ
