أَخْبَرَنَا إِسْمَاعِيل بْنُ إِبْرَاهِيمَ، عَنْ هُشَيْمٍ، عَنْ مُغِيرَةَ، عَنْ إِبْرَاهِيمَ، قَالَ: "كَانُوا إِذَا أَتَوْا الرَّجُلَ لِيَأْخُذُوا عَنْهُ، نَظَرُوا إِلَى صَلَاتِهِ، وَإِلَى سَمْتِهِ، وَإِلَى هَيْئَتِهِ".
Ibrahim al-Nakha'i, may Allah have mercy on him, said: (The righteous predecessors) when they went to someone to take knowledge of hadith, they would carefully observe his prayer, manner, and appearance. Then they would take hadith from him.
