أَخْبَرَنَا عُبَيْدُ اللَّهِ بْنُ سَعِيدٍ قَالَ سَمِعْتُ أَبَا أُسَامَةَ يَقُولُ مَا رَأَيْتُ رَجُلًا أَطْلَبَ لِلْعِلْمِ مِنْ عَبْدِ اللَّهِ بْنِ الْمُبَارَکِ الشَّامَاتِ وَمِصْرَ وَالْيَمَنَ وَالْحِجَازَ
سنن نسائی · Hadith 5768
‘Ubaidullah bin Saeed said: “I heard Abu Usamah say: ‘I never saw any man more assiduous in seeking knowledge than ‘Abdullah bin Al-Mubarak, not in Ash-Sham, Egypt, Yemen or the ijaz.” (Sahih)
