[Machine] About Umar, neither of them realized Umar, nor did they approach that. Ash-Shafi'i said, "The hadith of Sa'd is more authentic than the hadith of Umar because it is narrated by Rukayn bin ar-Rabi' from his father that Sa'd did it." And the hadith of Umar is mursal.
عَنْ عُمَرَ وَكِلَاهُمَا لَمْ يُدْرِكْ عُمَرَ ؓ وَلَا قَارَبَ ذَلِكَ قَالَ الشَّافِعِيُّ وَحَدِيثُ سَعْدٍ أَثْبَتُ مِنَ الْحَدِيثِ عَنْ عُمَرَ ؓ؛ لِأَنَّهُ عَنِ الرُّكَيْنِ بْنِ الرَّبِيعِ عَنْ أَبِيهِ أَنَّ سَعْدًا فَعَلَهُ بِهِ وَالْحَدِيثُ عَنْ عُمَرَ ؓ مُرْسَلٌ
