الإمام علي (عليه السَّلام):
أوحَى اللّهُ عَزَّ و جلَّ إلى داوودَ عليه السلام: إنّكَ نِعمَ العَبدُ لَولا أنّكَ تأكُلُ مِن بَيتِ المالِ و لا تَعمَلُ بِيَدِكَ شيئا. قالَ: فبَكى داوودُ عليه السلام، فأوحَى اللّه عَزَّ و جلَّ إلَى الحَديدِ: أنْ لِنْ لِعَبدي داوودَ، فلانَ، فألانَ اللّهُ تعالى لَهُ الحَديدَ، فكانَ يَعمَلُ كلَّ يَومٍ دِرعا فيَبيعُها بألفِ دِرهَمٍ، فعَمِلَ عليه السلام ثلاثَمِائةٍ و سِتّينَ دِرعا فباعَها بثلاثِمِائةٍ و سِتِّينَ ألفا، و استَغنى عن بَيتِ المالِ.
Imam Ali (as):
Allah Almighty revealed to David (as), You would be a great worshipper, if it was not for the fact that you consume from the treasury and do not labour at all with your own hands. David (as) then started crying, then Allah revealed unto the iron, Soften yourself for my worshipper David, and it did. So, Allah softened the metal for him, and after that he would make an armour shield every day, and would sell it for one thousand dirhams. He made three hundred and sixty shields and sold them for three hundred and sixty thousand dirhams, and hence he no longer needed the treasury.
