The Meaning of Cheating
Ghishsh linguistically: is the opposite of advice. Ghashshahu yaghushshuhu ghishsha is said if one did not truly advise another, displaying to him other than what we internally withheld.  al-Nihayah, Ibn al-Ahir (3/369); Lisan al-`Arab, Ibn Manzur (6/323); Taj al-`Arus, al-Zabidi (17/289-290).
Ghishsh technically: is concealing that which would be disliked if it were known by the buyer. It is also described as the state where a seller is aware of a matter with a product that, had the buyer been aware of it, he would not have given for it what he did in return.  al-Dhakhirah wa al-Qarafi (5/172); al-Zawajir, al-Haytami (1/396).

Whoever cheats is not from me.”  Reported by Muslim (102).
❖ He ﷺ from the narration of Ma`qal ibn Yasar, Allah be pleased with him: “there is not a slave of Allah whom Allah gives responsibility over others then dies having cheated them but that Allah makes the Garden impermissible for him.”  Reported by al-Bukhari (7150) and Muslim (142), and this is his wording.

We then heard a woman say to her daughter: ‘My daughter, mix this milk with water.’ She replied: ‘Mother, have you not heard what the Commander of the Faithful ordained today?’ She said: ‘What’s that, daughter of mine?’ ‘He commanded his caller to announce among the people that milk is not to be mixed with water.’ She said to her: ‘Daughter, go mix it with water, for neither the Commander of the Faithful nor his caller can see you here.’ The girl said to her mother: ‘Mother, I will not obey him openly yet disobey him privately.’  Reported by Ibn `Asakir in Tarikh Dimashq (70/253). Cheating in Poetry
The poet said:
The cheating person is feared, the advisor is secure,
The reckless is confuted, and the rightful is victorious.
The truthful is never doubtful, justice stands upright
On the roads of truth, and fraud is bent and crooked.
