Hadith on Justice: Must apply legal punishments with due process

Abu Huraira reported: Sa’d ibn ‘Ubadah said, “O Messenger of Allah, if I find another man with my wife, should I leave him alone until I bring four witnesses?” The Messenger of Allah, peace and blessings be upon him, said, “Yes.” Sa’d said, “Never! By the one who sent you with the truth, if that happened to me I would quickly grab the sword!” The Prophet said, “Listen to what your leader is saying. Verily, he has a sense of honor, and I have a greater sense of honor than him, and Allah has a greater sense of honor than me.”

عَنْ أَبِي هُرَيْرَةَ قَالَ قَالَ سَعْدُ بْنُ عُبَادَةَ يَا رَسُولَ اللَّهِ لَوْ وَجَدْتُ مَعَ أَهْلِي رَجُلًا لَمْ أَمَسَّهُ حَتَّى آتِيَ بِأَرْبَعَةِ شُهَدَاءَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ نَعَمْ قَالَ كَلَّا وَالَّذِي بَعَثَكَ بِالْحَقِّ إِنْ كُنْتُ لَأُعَاجِلُهُ بِالسَّيْفِ قَبْلَ ذَلِكَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ اسْمَعُوا إِلَى مَا يَقُولُ سَيِّدُكُمْ إِنَّهُ لَغَيُورٌ وَأَنَا أَغْيَرُ مِنْهُ وَاللَّهُ أَغْيَرُ مِنِّي
