Such a person forges an impression before the public by donning the dress of ascetics, scholars, or the wealthy so that people are taken in by him, even though he possesses none of those qualities. Other explanations have been offered, and Allah knows best.
[Commentary]
The author—may Allah have mercy on him—entitles this section of Riyad al-Salihin, “The Duty to Verify Whatever One Says or Relates.” After mentioning the prohibition of lying—defined as reporting something contrary to the facts—he follows it with this chapter to stress that a person must ascertain the accuracy of anything he transmits or utters, especially in times dominated by whims, endless chatter, and talk about events that may or may not have occurred.
