Be cautious about ahadith except those which were current during the reign of Umar, for he exhorted people to fear Allah, the Exalted and mMajestic. I heard the Messenger of Allah ﷺ as saying: He upon whom Allah intends to bestow goodness, He confers upon him an insight in religion; and I heard the Messenger of Allah ﷺ as saying: I am the treasurer. To one whom I give out of (my own) sweet will, he would be blessed in that, but he whom I give (yielding to) his constant begging and for his covetousness is like one who would eat, but would not be satisfied.  

سَمِعْتُ مُعَاوِيَةَ يَقُولُ إِيَّاكُمْ وَأَحَادِيثَ إِلاَّ حَدِيثًا كَانَ فِي عَهْدِ عُمَرَ فَإِنَّ عُمَرَ كَانَ يُخِيفُ النَّاسَ فِي اللَّهِ ﷻ سَمِعْتُ رَسُولَ اللَّهِ ﷺ وَهُوَ يَقُولُ مَنْ يُرِدِ اللَّهُ بِهِ خَيْرًا يُفَقِّهْهُ فِي الدِّينِ وَسَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ إِنَّمَا أَنَا خَازِنٌ فَمَنْ أَعْطَيْتُهُ عَنْ طِيبِ نَفْسٍ فَيُبَارَكُ لَهُ فِيهِ وَمَنْ أَعْطَيْتُهُ عَنْ مَسْأَلَةٍ وَشَرَهٍ كَانَ كَالَّذِي يَأْكُلُ وَلاَ يَشْبَعُ  

[Machine] "I heard Muawiyah saying, 'Beware of the Hadith of the Messenger of Allah, except for a Hadith from the time of Umar, and indeed Umar feared people for the sake of Allah.' I heard the Messenger of Allah saying, 'Whomsoever Allah wishes good for, He grants understanding of the religion to him.'"  

سَمِعْتُ مُعَاوِيَةَ يُحَدِّثُ وَهُوَ يَقُولُ إِيَّاكُمْ وَأَحَادِيثَ رَسُولِ اللهِ ﷺ إِلَّا حَدِيثًا كَانَ عَلَى عَهْدِ عُمَرَ وَإِنَّ عُمَرَ كَانَ أَخَافَ النَّاسَ فِي اللهِ ﷻ سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ مَنْ يُرِدِ اللهُ بِهِ خَيْرًا يُفَقِّهْهُ فِي الدِّينِ

(Using translation from Muslim 1037a)  

سَمِعْتُ مُعَاوِيَةَ يَقُولُ عَلَى مِنْبَرِ دِمِشْقَ إِيَّاكُمْ وَأَحَادِيثَ رَسُولِ اللَّهِ ﷺ إِلَّا حَدِيثًا كَانَ فِي عَهْدِ عُمَرَ فَإِنَّ عُمَرَ كَانَ يُخِيفُ النَّاسَ فِي اللَّهِ سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ «مَنْ يُرِدِ اللَّهُ بِهِ خَيْرًا يُفَقِّهْهُ فِي الدِّينِ» وَسَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ «إِنَّمَا أَنَا خَازِنٌ فَمَنْ أَعْطَيْتُهُ عَنْ طِيبِ نَفْسٍ يُبَارَكُ لَهُ فِيهِ وَمَنْ أَعْطَيْتُهُ عَنْ مَسْأَلَةٍ وَعَنْ شَرَهٍ كَانَ كَالَّذِي يَأْكُلُ وَلَا يَشْبَعُ»
