(14) باب فِيمَنْ يُعِينُ عَلَى خُصُومَةٍ مِنْ غَيْرِ أَنْ يَعْلَمَ أَمْرَهَا
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.
