وَعَنْ أَبِي ذَرٍّ رضى الله عنه
«قَالَ: سَأَلْتُ اَلنَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ أَيُّ اَلْعَمَلِ أَفْضَلُ? قَالَ: «إِيمَانٌ بَِاللَّهِ، وَجِهَادٌ فِي سَبِيلِهِ». قُلْتُ: فَأَيُّ اَلرِّقَابِ أَفْضَلُ? قَالَ: «أَعْلَاهَ ا ثَمَنًا، وَأَنْفَسُهَا عِنْدَ أَهْلِهَا»
I asked the Messenger of Allah (sallallahu alayhi wa sallam) ‘Which action is the most excellent?’ He replied, “Faith in Allah and Jihad in His Cause.” I then asked, ‘Which slaves are the most excellent (for the purpose of emancipating them)’ and he replied, “Those whose prices are the highest and are the most valuable to their owners.” Agreed upon.
