Yahya ibn Rashid said:We were sitting waiting for Abdullah ibn Umar who came out to us and sat. He then said: I heard the Messenger of Allah (ﷺ) as saying: If anyone's intercession intervenes as an obstacle to one of the punishments prescribed by Allah, he has opposed Allah; if anyone disputes knowingly about something which is false, he remains in the displeasure of Allah till he desists, and if anyone makes an untruthful accusation against a Muslim, he will be made by Allah to dwell in the corrupt fluid flowing from the inhabitants of Hell till he retracts his statement.
حَدَّثَنَا أَحْمَدُ بْنُ يُونُسَ، حَدَّثَنَا زُهَيْرٌ، حَدَّثَنَا عُمَارَةُ بْنُ غَزِيَّةَ، عَنْ يَحْيَى بْنِ رَاشِدٍ، قَالَ جَلَسْنَا لِعَبْدِ اللَّهِ بْنِ عُمَرَ فَخَرَجَ إِلَيْنَا فَجَلَسَ فَقَالَ سَمِعْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم يَقُولُ " مَنْ حَالَتْ شَفَاعَتُهُ دُونَ حَدٍّ مِنْ حُدُودِ اللَّهِ فَقَدْ ضَادَّ اللَّهَ وَمَنْ خَاصَمَ فِي بَاطِلٍ وَهُوَ يَعْلَمُهُ لَمْ يَزَلْ فِي سَخَطِ اللَّهِ حَتَّى يَنْزِعَ عَنْهُ وَمَنْ قَالَ فِي مُؤْمِنٍ مَا لَيْسَ فِيهِ أَسْكَنَهُ اللَّهُ رَدْغَةَ الْخَبَالِ حَتَّى يَخْرُجَ مِمَّا قَالَ " .
