Habib al-Maliki said:

A man said to Imran ibn Husayn: AbuNujayd, you narrate to us traditions whose basis we do not find in the Qur'an.

Thereupon, Imran got angry and said to the man: Do you find in the Qur'an that one dirham is due on forty dirhams (as Zakat), and one goat is due on such-and-such number of goats, and one camel will be due on such-and-such number of camels?

He replied: No.

He said: From whom did you take it? You took it from us, from the Messenger of Allah ﷺ.

He mentioned many similar things.

حَدَّثَنَا مُحَمَّدُ بْنُ بَشَّارٍ، حَدَّثَنِي مُحَمَّدُ بْنُ عَبْدِ اللَّهِ الأَنْصَارِيُّ، حَدَّثَنَا صُرَدُ بْنُ أَبِي الْمَنَازِلِ، قَالَ سَمِعْتُ حَبِيبًا الْمَالِكِيَّ، قَالَ قَالَ رَجُلٌ لِعِمْرَانَ بْنِ حُصَيْنٍ يَا أَبَا نُجَيْدٍ إِنَّكُمْ لَتُحَدِّثُونَنَا بِأَحَادِيثَ مَا نَجِدُ لَهَا أَصْلاً فِي الْقُرْآنِ . فَغَضِبَ عِمْرَانُ وَقَالَ لِلرَّجُلِ أَوَجَدْتُمْ فِي كُلِّ أَرْبَعِينَ دِرْهَمًا دِرْهَمٌ وَمِنْ كُلِّ كَذَا وَكَذَا شَاةً شَاةٌ وَمِنْ كُلِّ كَذَا وَكَذَا بَعِيرًا كَذَا وَكَذَا أَوَجَدْتُمْ هَذَا فِي الْقُرْآنِ قَالَ لاَ . قَالَ فَعَنْ مَنْ أَخَذْتُمْ هَذَا أَخَذْتُمُوهُ عَنَّا وَأَخَذْنَاهُ عَنْ نَبِيِّ اللَّهِ ﷺ وَذَكَرَ أَشْيَاءَ نَحْوَ هَذَا .
