Abu Qilaba reported that 'Abdullah said to Abu Mas'ud - or
Abu Mas'ud said to 'Abdullah, "What did you hear the Prophet, may Allah
bless him and grant him peace, say about '(false) assertion?" He said,
"It is a bad mount for a man."
حَدَّثَنَا مَخْلَدُ بْنُ مَالِكٍ، قَالَ: حَدَّثَنَا حَجَّاجُ بْنُ مُحَمَّدٍ، قَالَ: أَخْبَرَنَا مُبَارَكُ بْنُ فَضَالَةَ، عَنْ بَكْرِ بْنِ عَبْدِ اللهِ الْمُزَنِيِّ، عَنْ عَدِيِّ بْنِ أَرْطَأَةَ قَالَ: كَانَ الرَّجُلُ مِنْ أَصْحَابِ النَّبِيِّ صلى الله عليه وسلم إِذَا زُكِّيَ قَالَ: اللَّهُمَّ لاَ تُؤَاخِذْنِي بِمَا يَقُولُونَ، وَاغْفِرْ لِي مَا لا يَعْلَمُونَ.
'Adi ibn Arta' said, "When one of the Companions of the Prophet,
may Allah bless him and grant him peace, was praised, he said in supplication
to Allah), 'Do not take me to task for what they say and forgive me for
what they do not know.'"
'Abdullah ibn 'Amr said, "Abu Mas'ud, what did you hear the Messenger
of Allah, may Allah bless him and grant him peace, say about 'People who
make false claims?" He replied, "I heard him say, 'A bad mount for a man'
and I heard him say, 'Cursing a believer is like killing him.'"
'Abdullah ibn Burayda reported from his father that the Messenger
of Allah, may Allah bless him and grant him peace, said, "Do not call a
hypocrite 'master'. He is not your master and you will have angered your
Lord, the Mighty and Exalted."
