Among the Various Forms of Lying We Must Avoid
Shaikh Rabīʿ ibn Hādī Al-Madkhalī, may Allāh protect him, said:
Cheating [and misrepresentation] in [one’s] dealings, having an intention to go back on [one’s] promises [and commitments], and performing [good] deeds for others to see and praise that: all of those things are forms of lying.
