The Meaning of Greed
Tama` linguistically: tami`a tam`a fa-huwa tami` (he is greedy). Atma`ahu ghayrih (someone enticed him to greed). He is tami` means one is covetous.  Kitab al-`Ayn, al-Khalil (2/27).
Tama` technically: is the self’s calling towards a thing out of desire for it. It is also said that it is humiliation which is begotten out of covetousness, and falsehood ignorance of Allah’s wisdom.  al-Mufradat, al-Raghib (); al-Tawqif `ala Muimmat al-Ta`arif, al-Manawi (p. 228). The Difference between Greed and Some Other Characteristics  al-Furuq al-Lughawiyyah, al-`Askari (p. 73, 248).
● The Difference between Greed and Covetousness (Hirs)
They say covetousness is more severe than greed.
● The Difference between Greed and Wishing (Amal)
Wishing is usually used for what is unlikely to happen. Whoever has decided to travel to a far land says: ‘I wish to reach it.’ He does not say ‘I am greedy to reach it’, unless he is close by. Greed is only for what is close and achievable. Wishing may come with the same meaning as greed though.
● The Difference between Greed and Hopefulness (Raja’)
Hope is one’s belief that good will reach him despite having some doubt therein, though his belief that it will is greater than his doubt it won’t. Nonetheless, it is not borne of knowledge. Greed manifests without something that calls for it. If one is greedy for a thing, it is as if one has enticed himself with it, without there being reason for it.Dispraise of Greed in the Qur’an and Sunnah
❖ Allah, exalted, says: “Do not sell My messages for a small price.” al-Baqarah: 41. Meaning, do not take little to satisfy your greed and withhold Allah's name. The price is their greed.  Tafsir al-Qur’an al-`Azim, Ibn Abi Hatim (1/97).
❖ He, honoured be His mention, says: “Many partners treat each other unfairly.” Sad: 24. Meaning, they do so out of greed, covetousness, love of abundant wealth, all guiding towards falsehood if Allah is not kind to them and shows them grace.  Bayan al-Ma`ani, al-`Ani (1/304).
❖ Ka`b ibn Malik al-Ansari, Allah be pleased with him, said that the Prophet ﷺ said: “That two wolves are set loose on a flock of sheep is less harmful on them than the harm of covetousness with wealth and prestige for over the religion of man.”  Reported by al-Tirmidhi (2376) and Ahmad (15794). al-Tirmidhi said: “It is sound, authentic.” It is authenticated by al-Albani in Sahih Sunan al-Tirmidhi (2376). Meaning, that man’s care for these things is more harmful to his religion - metaphorically referred to as a flock of sheep - due to his weakness and covetousness, than two wolves with the flock.  Mirqat al-Mafatih Sharh Mishkat al-Masabih, al-Qari (8/3304).
❖ `Ubadah ibn al-Samit, Allah be pleased with him, said: “Allah’s Messenger ﷺ said: ‘Whoever joins a conquest for the sake of Allah but intends no more than the spoils of war, then he will get what he intended.’”  Reported by al-Nasa’i (3138) and Ahmad (22692). al-Shawkani authenticated it in al-Fath al-Rabbani (12/6233), and al-Albani graded it as sound in Sahih Sunan al-Nasa’i (3138). Quotes of the Predecessors and Scholars on Dispraising Greed

❖ `Ali, Allah be pleased with him, said: “Most deaths of the intellect come under the lightning of greed.”  al-Mustatraf, al-Abhishi (p. 83).
