"When the slave (of Allah) lies, the angel goes a mile away from him because of the stench of what he has done."Yahya said: "(I asked) 'Abdur-Rahim bin Harun if he approved of it,and he said 'Yes'."
Jami` at-Tirmidhi Book 27, Hadith 78
← Previous Hadith "Abide by truthfulness. For indeed truthfulness leads to righteousness. And indeed righteousness leads to Paradise. A man continues telling the truth and trying hard to tell the truth until he is recorded with Allah as a truthful person. Refrain from falsehood. For indeed falsehood leads to wickedness, and wickedness leads to the Fire. A slave (of Allah) continues lying and trying hard to lie, until he is recorded with Allah as a liar."
