Hadith 644
أَخْبَرَنَا جَعْفَرُ بْنُ عَوْنٍ، أَنْبَأَنَا أَبُو عُمَيْسٍ، عَنْ الْقَاسِمِ، قَالَ: قَالَ عَبْدُ اللَّهِ رَضِيَ اللهُ عَنْهُ: "آفَةُ الْحَدِيثِ النِّسْيَانُ".
It is narrated from Qasim bin Abdur Rahman Masoodi that Sayyiduna Abdullah bin Masood (may Allah be pleased with him) said: The calamity of Hadith is forgetfulness (i.e., to forget it).
