عَنْ أَبِي مُرَاوِحٍ عَنْ أَبِي ذَرٍّ رَضِيَ اللَّهُ عَنْهُ قَالَ قُلْتُ يَا رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ أَيُّ الْعَمَلِ أَفْضَلُ قَالَ إِيمَانٌ بِاللَّهِ تَعَالَى وَجِهَادٌ فِي سَبِيلِهِ قُلْتُ يَا رَسُولَ اللَّهِ فَأَيُّ الرِّقَابِ أَفْضَلُ قَالَ أَنْفَسُهَا عِنْدَ أَهْلِهَا وَأَغْلَاهَا ثَمَنًا قَالَ فَإِنْ لَمْ أَجِدْ قَالَ تُعِينُ صَانِعًا أَوْ تَصْنَعُ لِأَخْرَقَ وَقَالَ فَإِنْ لَمْ أَسْتَطِعْ قَالَ كُفَّ أَذَاكَ عَنِ النَّاسِ فَإِنَّهَا صَدَقَةٌ تَصَدَّقُ بِهَا عَنْ نَفْسِكَ
It is narrated from Sayyiduna Abu Dharr (may Allah be pleased with him), he says: I asked, "O Messenger of Allah! Which deed is the best?" He (peace and blessings be upon him) said: "To have faith in Allah and to strive in His path." I said: "Which slave is best to set free?" He (peace and blessings be upon him) said: "The one who is most excellent and most valuable in the eyes of his owners." I said: "If I am not able to do that?" He (peace and blessings be upon him) replied: "Then help someone who is skilled, or do some work for someone who is unskilled." I said: "If I am unable to do even that?" He (peace and blessings be upon him) said: "Then keep people safe from your evil; this too will be a charity from you for yourself."
