Riyad as-Salihin 1359
Abu Dharr (May Allah be pleased with him) reported:
I asked the Messenger of Allah (ﷺ), "Which deed is most excellent?" He replied, "Faith in Allah and Jihad in His path." I then asked, "Which slaves are most excellent (to set free)?" He replied, "Those who are held in high esteem by their people and whose value is higher." [Al- Bukhari and Muslim] .
وعن أبي ذر رضي الله عنه قال‏:‏ قلت يا رسول الله أي الأعمال أفضل‏؟‏ قال‏:‏ ‏"‏الإيمان بالله، والجهاد في سبيل الله‏"‏ قلت‏:‏ أي الرقاب أفضل‏؟‏ قال‏:‏ ‏"‏أنفسها عند أهلها وأكثرها ثمنًا” ‏(‏‏(‏متفق عليه‏)‏‏)‏
