30) Telling lies
Allah Most High states,
{Then let us earnestly pray and invoke the curse of Allah on those who lie!} (Al-’Imran: 61)
{Allah guides not one who transgresses and lies!} (Ghafir: 28)
{Cursed be the conjecturers (the liars).} (Al-Dhariyat: 10)
On the authority of Ibn Mas’ud (may Allah be pleased with him), “the Messenger of Allah (pbuh) said,
“Adhere firmly to truthfulness for truthfulness surely leads to righteousness and righteousness leads to Paradise, and a man is recorded with Allah as a sincere one as long as he is truthful. However, lying leads to immorality and immorality leads to the Hell-Fire, and a man is recorded with Allah as a liar as long as he lies.” (Bukhari and Muslim)
