[Machine] We were with the Messenger of Allah ﷺ when he said, "Shall I not inform you of the greatest of the major sins?" They said, "Certainly, O Messenger of Allah." He said, "Associating partners with Allah and disobedience to parents." He was reclining, then he sat up and said, "And false testimony, and false testimony, and false testimony, or false speech." The Messenger of Allah ﷺ kept repeating it until we said, "We wish he would stop."  

كُنَّا عِنْدَ رَسُولِ اللهِ ﷺ فَقَالَ أَلَا أُحَدِّثُكُمْ بِأَكْبَرِ الْكَبَائِرِ؟ الْإِشْرَاكُ بِاللهِ وَعُقُوقُ الْوَالِدَيْنِ قَالَ وَكَانَ مُتَّكِئًا فَجَلَسَ وَقَالَ وَشَهَادَةُ الزُّورِ وَشَهَادَةُ الزُّورِ وَشَهَادَةُ الزُّورِ أَوْ قَوْلُ الزُّورِ فَمَا زَالَ رَسُولُ اللهِ ﷺ يُكَرِّرُهَا حَتَّى قُلْنَا لَيْتَهُ سَكَتَ  

[Machine] It was mentioned in the presence of the Messenger of Allah ﷺ that a man testifies with a testimony. So he said: "As for you, O Ibn Abbas, do not testify except for a matter that is clear to you like the brightness of this sun." And the Messenger of Allah ﷺ pointed with his hand towards the sun and said: "Muhammad ibn Sulaiman ibn Masmaul spoke about this." Al-Humaidi spoke about it, but it is not known if it was reliable or not. And Allah knows best.  

ذُكِرَ عِنْدَ رَسُولِ اللهِ ﷺ الرَّجُلُ يَشْهَدُ بِشَهَادَةٍ فَقَالَ أَمَّا أَنْتَ يَا ابْنَ عَبَّاسٍ فَلَا تَشَهَدْ إِلَّا عَلَى أَمْرٍ يُضِيءُ لَكَ كَضِيَاءِ هَذِهِ الشَّمْسِ وَأَوْمَى رَسُولُ اللهِ ﷺ بِيَدِهِ إِلَى الشَّمْسِ مُحَمَّدُ بْنُ سُلَيْمَانَ بْنِ مَسْمُولٍ هَذَا تَكَلَّمَ فِيهِ الْحُمَيْدِيُّ وَلَمْ يُرْوَ مِنْ وَجْهٍ يُعْتَمَدُ عَلَيْهِ وَاللهُ أَعْلَمُ  

[Machine] I said to Ibn Umar, "Indeed, people are inviting me to bear witness and I dislike that." He said, "Bear witness to what you know."  

قُلْتُ لِابْنِ عُمَرَ إِنَّ نَاسًا يَدْعُونَنِي يُشْهِدُونَنِي وَأَكْرَهُ ذَاكَ قَالَ اشْهَدْ بِمَا تَعْلَمُ
