Narrated Abu Musa: I went along with two men to see the Prophet (ﷺ). One of them recited tashahhud and said: We have come to you so that you may employ us for your work. The other also said the same thing. He (the Prophet) replied: The most faithless of you in our eyes is the one who asked for it (responsible post). Abu Musa then apologized to the Prophet (ﷺ) and said: I did not know why they came to you. He did not employ them for anything until he died.

حَدَّثَنَا وَهْبُ بْنُ بَقِيَّةَ، حَدَّثَنَا خَالِدٌ، عَنْ إِسْمَاعِيلَ بْنِ أَبِي خَالِدٍ، عَنْ أَخِيهِ، عَنْ بِشْرِ بْنِ قُرَّةَ الْكَلْبِيِّ، عَنْ أَبِي بُرْدَةَ، عَنْ أَبِي مُوسَى، قَالَ انْطَلَقْتُ مَعَ رَجُلَيْنِ إِلَى النَّبِيِّ صلى الله عليه وسلم فَتَشَهَّدَ أَحَدُهُمَا ثُمَّ قَالَ جِئْنَا لِتَسْتَعِينَ بِنَا عَلَى عَمَلِكَ . وَقَالَ الآخَرُ مِثْلَ قَوْلِ صَاحِبِهِ . فَقَالَ " إِنَّ أَخْوَنَكُمْ عِنْدَنَا مَنْ طَلَبَهُ " . فَاعْتَذَرَ أَبُو مُوسَى إِلَى النَّبِيِّ صلى الله عليه وسلم وَقَالَ لَمْ أَعْلَمْ لِمَا جَاءَا لَهُ . فَلَمْ يَسْتَعِنْ بِهِمَا عَلَى شَىْءٍ حَتَّى مَاتَ .
