أَخْبَرَنَا مُحَمَّدُ بْنُ عِيسَى، حَدَّثَنَا عَبَّادٌ، عَنْ حُصَيْنٍ، عَنْ إِبْرَاهِيمَ، قَالَ: "كَانَ عَبِيدَةُ يَأْتِي عَبْدَ اللَّهِ رَضِيَ اللهُ عَنْهُ كُلَّ خَمِيسٍ، فَيَسْأَلُهُ عَنْ أَشْيَاءَ غَابَ عَنْهَا، فَكَانَ عَامَّةُ مَا يُحْفَظُ عَنْ عَبْدِ اللَّهِ مِمَّا يَسْأَلُهُ عَبِيدَةُ عَنْهُ".
It is narrated from Ibrahim that Ubaidah (bin Amr al-Sulmani) used to visit Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) every Thursday and would ask about matters that he did not understand. Therefore, generally, whatever Ibrahim had from Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) were those issues which Ubaidah used to ask him about.
