عَنْ رِفَاعَةَ بْنِ رَافِعٍ - رضى الله عنه - أَنَّ اَلنَّبِيَّ - صلى الله عليه وسلم -سُئِلَ: أَيُّ اَلْكَسْبِ أَطْيَبُ? قَالَ: { عَمَلُ اَلرَّجُلِ بِيَدِهِ, وَكُلُّ بَيْعٍ مَبْرُورٍ } رَوَاهُ اَلْبَزَّارُ، وَصَحَّحَهُ اَلْحَاكِمُ. [1] .
Narrated Rifa'a bin Rafi' (RA): The Prophet (ﷺ) was asked, 'What type of earning is best?' He replied, "A man's work with his hand and every transaction which is free from cheating or deception." [Reported by al-Bazzar; al-Hakim graded it Sahih (authentic)].
