[Machine] "To curse the Messenger of Allah ﷺ , one of them said to his companion, 'Do not curse him, by Allah, if he is a prophet, then we would be doomed.' Khalef replied, 'Let us curse, for we will never prosper, neither in this life nor in the Hereafter.' They approached him and said, 'We will not curse you, but we will give you what you asked for, so send an honest man with us.' The Prophet ﷺ said, 'I will send an honest man, a truly honest man.' He then sought the opinion of the Companions of Muhammad, and they said, 'Stand up, Abu 'Ubaydah ibn al-Jarrah.' When he stood up, the Prophet ﷺ said, 'This is the honest man of this nation.'"  

أحمد:٣٩٣٠ – حَدَّثَنَا أَسْوَدُ قَالَ وَأَخْبَرَنَا خَلَفُ بْنُ الْوَلِيدِ حَدَّثَنَا إِسْرَائِيلُ عَنْ أَبِي إِسْحَاقَ عَنْ صِلَةَ عَنِ ابْنِ مَسْعُودٍ قَالَ جَاءَ الْعَاقِبُ وَالسَّيِّدُ صَاحِبَا نَجْرَانَ قَالَ وَأَرَادَا

أَنْ يُلَاعِنَا رَسُولَ اللهِ ﷺ قَالَ فَقَالَ أَحَدُهُمَا لِصَاحِبِهِ لَا تُلَاعِنْهُ فَوَاللهِ لَئِنْ كَانَ نَبِيًّا فَلَعَنَّا قَالَ خَلَفٌ فَلَاعَنَّا لَا نُفْلِحُ نَحْنُ وَلَا عَقِبُنَا أَبَدًا قَالَ فَأَتَيَاهُ فَقَالَا لَا نُلَاعِنُكَ وَلَكِنَّا نُعْطِيكَ مَا سَأَلْتَ فَابْعَثْ مَعَنَا رَجُلًا أَمِينًا فَقَالَ النَّبِيُّ ﷺ لَأَبْعَثَنَّ رَجُلًا أَمِينًا حَقَّ أَمِينٍ حَقَّ أَمِينٍ قَالَ فَاسْتَشْرَفَ لَهَا أَصْحَابُ مُحَمَّدٍ قَالَ فَقَالَ قُمْ يَا أَبَا عُبَيْدَةَ بْنَ الْجَرَّاحِ قَالَ فَلَمَّا قَفَّاقَالَ هَذَا أَمِينُ هَذِهِ الْأُمَّةِ

Al-ʿAqib and Saiyid, the rulers of Najran, came to Messenger of Allah ﷺ with the intention of doing Lian one of them said to the other, "Do not do (this Lian) for, by Allah, if he is a Prophet and we do this Lian, neither we, nor our offspring after us will be successful." Then both of them said (to the Prophet ﷺ ), "We will give what you should ask but you should send a trustworthy man with us, and do not send any person with us but an honest one." The Prophet ﷺ said, "I will send an honest man who Is really trustworthy." Then every one of the companions of Messenger of Allah ﷺ wished to be that one. Then the Prophet said, "Get up, O Abu 'Ubaida bin Al-Jarrah." When he got up, Messenger of Allah ﷺ said, "This is the Trustworthy man of this (Muslim) nation."
