“Indeed, fear of people should not prevent a man from speaking the truth, if he knows it.” Then Abu Sa'eed wept and said: "By Allah, we have seen things that made us scared (and we did not speak up)."  

ابن ماجة:٤٠٠٧حَدَّثَنَا عِمْرَانُ بْنُ مُوسَى أَنْبَأَنَا حَمَّادُ بْنُ زَيْدٍ حَدَّثَنَا عَلِيُّ بْنُ زَيْدِ بْنِ جُدْعَانَ عَنْ أَبِي نَضْرَةَ عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ

أَنَّ رَسُولَ اللَّهِ ﷺ قَامَ خَطِيبًا فَكَانَ فِيمَا قَالَ أَلاَ لاَ يَمْنَعَنَّ رَجُلاً هَيْبَةُ النَّاسِ أَنْ يَقُولَ بِحَقٍّ إِذَا عَلِمَهُ قَالَ فَبَكَى أَبُو سَعِيدٍ وَقَالَ قَدْ وَاللَّهِ رَأَيْنَا أَشْيَاءَ فَهِبْنَا

[Machine] The Messenger of Allah, ﷺ , said, "A person's reputation should not prevent him from standing up for what is right, once he knows about it." Then Abu Sa'eed cried and said, "By Allah, we have indeed witnessed this, and we did stand up for it."  

أحمد:١١٦٧٨حَدَّثَنَا عَفَّانُ حَدَّثَنَا حَمَّادٌ عَنْ عَلِيِّ بْنِ زَيْدٍ عَنِ الْحَسَنِ أَنَّ أَبَا سَعِيدٍ الْخُدْرِيَّ قَالَ

قَالَ رَسُولُ اللهِ ﷺ لَا يَمْنَعَنَّ رَجُلًا مَهَابَةُ النَّاسِ أَنْ يَقُومَ بِحَقٍّ إِذَا عَلِمَهُ قَالَ ثُمَّ بَكَى أَبُو سَعِيدٍ قَالَ قَدْ وَاللهِ شَهِدْنَاهُ فَمَا قُمْنَا بِهِ
