Hadith 1402

حَدَّثَنَا الْحُسَيْنُ بْنُ إِسْمَاعِيلَ ، ثنا عَبْدُ اللَّهِ بْنُ شَبِيبٍ ، حَدَّثَنِي ذُؤَيْبُ بْنُ عِمَامَةَ ، ثنا عَبْدُ الْمُهَيْمِنِ بْنُ عَبَّاسٍ ، عَنْ أَبِيهِ ، عَنْ جَدِّهِ ، عَنِ الْمُنْذِرِ بْنِ عَمْرٍو ، وَكَانَ مِنَ النُّقَبَاءِ مِنْ بَنِي سَاعِدَةَ ، " أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ سَجَدَ سَجْدَتَيِ السَّهْوِ قَبْلَ التَّسْلِيمِ " .
Abdul Muhaymin narrates from his father, who narrates from his grandfather, Sayyiduna Mundhir bin Amr (may Allah be pleased with him), that he said: This companion was among the leaders (nuqaba) of Banu Sa'idah. He narrates: The Noble Prophet (peace and blessings be upon him) performed two prostrations of forgetfulness (sajda sahw) before saying the salam. According to one statement, this is the only narration transmitted from Sayyiduna Mundhir bin Amr (may Allah be pleased with him).
