Sahi is the person who is distinguished in the matter of jud (cūd, generosity). The generosity of this person may be for attaining a particular goal or for some reason. This is the initial maqām (spiritual station) of jud. Cevvād, on the other hand, is the one who is not distinguished in this way. His action has neither a specific goal nor a reason. These are the ḥāl (spiritual states) of two prophets: one is the Khalil (Abraham), the other is the Habib (the Beloved, i.e., Muhammad). (Hujwīrī, 380)
Sahi is the one who distributes part of his wealth and keeps part for himself. Cevvād is the one who gives away most of his wealth and keeps little for himself. The possessor of isār (altruism) is the one who endures hardship and harm, and does good with his provisions. Isār is the highest of the ranks, followed by jud, and then by sahā (generosity). (Jāmiʿ, 188)
