That he heard Messenger of Allah ﷺ saying, "If a judge gives a verdict according to the best of his knowledge and his verdict is correct (i.e. agrees with Allah and His Apostle's verdict) he will receive a double reward, and if he gives a verdict according to the best of his knowledge and his verdict is wrong, (i.e. against that of Allah and His Apostle) even then he will get a reward ."

أَنَّهُ سَمِعَ رَسُولَ اللَّهِ ﷺ يَقُولُ إِذَا حَكَمَ الْحَاكِمُ فَاجْتَهَدَ ثُمَّ أَصَابَ فَلَهُ أَجْرَانِ وَإِذَا حَكَمَ فَاجْتَهَدَ ثُمَّ أَخْطَأَ فَلَهُ أَجْرٌ قَالَ فَحَدَّثْتُ بِهَذَا الْحَدِيثِ أَبَا بَكْرِ بْنَ عَمْرِو بْنِ حَزْمٍ فَقَالَ هَكَذَا حَدَّثَنِي أَبُو سَلَمَةَ بْنُ عَبْدِ الرَّحْمَنِ عَنْ أَبِي هُرَيْرَةَ وَقَالَ عَبْدُ الْعَزِيزِ بْنُ الْمُطَّلِبِ عَنْ عَبْدِ اللَّهِ بْنِ أَبِي بَكْرٍ عَنْ أَبِي سَلَمَةَ عَنِ النَّبِيِّ ﷺ مِثْلَهُ

'If a judge passes a judgment having exerted himself to arrive at what is correct, and he is indeed correct, he will have two rewards. If he passes judgment having exerted himself to arrive at what is correct, but it is incorrect, he will have one reward.'" I narrated it to Abu Bakr bin Hazm and he said: "This is what Abu Salamah narrated to me from Abu Hurairah.

قَالَ رَسُولُ اللَّهِ ﷺ إِذَا حَكَمَ الْحَاكِمُ فَاجْتَهَدَ فَأَصَابَ فَلَهُ أَجْرَانِ وَإِذَا حَكَمَ فَاجْتَهَدَ فَأَخْطَأَ فَلَهُ أَجْرٌ فَحَدَّثْتُ بِهِ أَبَا بَكْرِ بْنَ حَزْمٍ فَقَالَ هَكَذَا حَدَّثَنِي أَبُو سَلَمَةَ عَنْ أَبِي هُرَيْرَةَ

"When the judge passes a judgement in which he strived and was correct, then he receives two rewards. And when he judges and is mistaken, then he receives one reward."

قَالَ رَسُولُ اللَّهِ ﷺ إِذَا حَكَمَ الْحَاكِمُ فَاجْتَهَدَ فَأَصَابَ فَلَهُ أَجْرَانِ وَإِذَا حَكَمَ فَأَخْطَأَ فَلَهُ أَجْرٌ وَاحِدٌ قَالَ وَفِي الْبَابِ عَنْ عَمْرِو بْنِ الْعَاصِي وَعُقْبَةَ بْنِ عَامِرٍ

“When the judge passes a judgement and does his best and gets it right, he will have two rewards, and if he passes a judgement and does his best and gets it wrong, he will have one reward.” (Sahih) Yazid (one of narrators) said : “So I Narrated it to Abu Bakr bin 'Amr bin Hazm. He said: 'This is how it was narrated to me by Abu Salamah from Abu Hurairah.'”

أَنَّهُ سَمِعَ رَسُولَ اللَّهِ ﷺ يَقُولُ إِذَا حَكَمَ الْحَاكِمُ فَاجْتَهَدَ فَأَصَابَ فَلَهُ أَجْرَانِ وَإِذَا حَكَمَ فَاجْتَهَدَ فَأَخْطَأَ فَلَهُ أَجْرٌ قَالَ يَزِيدُ فَحَدَّثْتُ بِهِ أَبَا بَكْرِ بْنَ عَمْرِو بْنِ حَزْمٍ فَقَالَ هَكَذَا حَدَّثَنِيهِ أَبُو سَلَمَةَ عَنْ أَبِي هُرَيْرَةَ

'If a judge passes a judgment having exerted himself to arrive at what is correct, and he is indeed correct, he will have two rewards. If he passes judgment having exerted himself to arrive at what is correct, but it is incorrect, he will have one reward.'" I narrated it to Abu Bakr bin Hazm and he said: "This is what Abu Salamah narrated to me from Abu Hurairah. (Using translation from Abū Dāʾūd 3574)

أَنَّهُ سَمِعَ رَسُولَ اللهِ ﷺ يَقُولُ إِذَا حَكَمَ الْحَاكِمُ فَاجْتَهَدَ فَأَصَابَ فَلَهُ أَجْرَانِ وَإِذَا حَكَمَ فَاجْتَهَدَ فَأَخْطَأَ فَلَهُ أَجْرٌ قَالَ فَحَدَّثْتُ بِهَذَا الْحَدِيثِ أَبَا بَكْرِ بْنَ عَمْرِو بْنِ حَزْمٍ قَالَ هَكَذَا حَدَّثَنِي أَبُو سَلَمَةَ بْنُ عَبْدِ الرَّحْمَنِ عَنْ أَبِي هُرَيْرَةَ

'If a judge passes a judgment having exerted himself to arrive at what is correct, and he is indeed correct, he will have two rewards. If he passes judgment having exerted himself to arrive at what is correct, but it is incorrect, he will have one reward.'" I narrated it to Abu Bakr bin Hazm and he said: "This is what Abu Salamah narrated to me from Abu Hurairah. (Using translation from Abū Dāʾūd 3574)

قَالَ رَسُولُ اللهِ ﷺ إِذَا حَكَمَ الْحَاكِمُ فَاجْتَهَدَ فَأَصَابَ فَلَهُ أَجْرَانِ وَإِنْ أَخْطَأَ فَلَهُ أَجْرٌ قَالَ يَزِيدُ فَذَكَرْتُ ذَلِكَ لِأَبِي بَكْرِ بْنِ حَزْمٍ فَقَالَ هَكَذَاحَدَّثَنِي بِهِ أَبُو سَلَمَةَ عَنْ أَبِي هُرَيْرَةَ عَنِ النَّبِيِّ ﷺ بِمِثْلِهِ

"The Messenger of Allah [SAW] said: 'If a judge passes judgment and strives to reach the right conclusion and gets it right, he will have two rewards; if he strives to reach the right conclusion but gets it wrong, he will still have one reward." (Using translation from Nasāʾī 5381)

قَالَ رَسُولُ اللَّهِ ﷺ «إِذَا حَكَمَ الْحَاكِمُ فَاجْتَهَدَ فَأَصَابَ فَلَهُ أَجْرَانِ وَإِذَا حَكَمَ فَاجْتَهَدَ فَأَخْطَأَ فَلَهُ أَجْرٌ»
