Sahih al-Bukhari · Book 83: Oaths and Vows · "I bear witness swearing by Allah"
Narrated `Abdullah:
حَدَّثَنَا سَعْدُ بْنُ حَفْصٍ ، حَدَّثَنَا شَيْبَانُ ، عَنْ مَنْصُورٍ ، عَنْ إِبْرَاهِيمَ ، عَنْ عَبِيدَةَ ، عَنْ عَبْدِ اللَّهِ ، قَالَ سُئِلَ النَّبِيُّ صلى الله عليه وسلم أَىُّ النَّاسِ خَيْرٌ قَالَ " قَرْنِي، ثُمَّ الَّذِينَ يَلُونَهُمْ، ثُمَّ الَّذِينَ يَلُونَهُمْ، ثُمَّ يَجِيءُ قَوْمٌ تَسْبِقُ شَهَادَةُ أَحَدِهِمْ يَمِينَهُ، وَيَمِينُهُ شَهَادَتَهُ " . قَالَ إِبْرَاهِيمُ وَكَانَ أَصْحَابُنَا يَنْهَوْنَا وَنَحْنُ غِلْمَانٌ أَنْ نَحْلِفَ بِالشَّهَادَةِ وَالْعَهْدِ .
The Prophet (ﷺ) was asked, "Who are the best people?" He replied: The people of my generation, and then those who will follow (come after) them, and then those who will come after the later; after that there will come some people whose witness will precede their oaths and their oaths will go ahead of their witness." Ibrahim (a sub-narrator) said, "When we were young, our elder friends used to prohibit us from taking oaths by saying, 'I bear witness swearing by Allah, or by Allah's Covenant."'
