Peace, one and all…
Imam Ja’far al-Sadiq (may God ennoble his countenance) said:
‘Futuwwah [spiritual chivalry] is not possible with quarreling and backbiting. Futuwwah is feeding people, giving to them, being pleasant and honourable to them and not causing them difficulty’
(Quoted in al-Sulami, The Way of Sufi Chivalry, 3.2 p.64)
