Imaam Ibnul Qayyim [rahimahullaah] said:

“Glorified be Allaah! How many a heart is decayed yet its owner is unaware of it! How many a [person] is put to trial by the praises he [receives] from the people, deceived by Allaah’s concealment of his [sins, shortcomings etc] and being gradually led to destruction through the blessings Allaah bestowed upon him [i.e. he utilizes those blessings to commit sins and feels safe from punishment]! All these affairs are a punishment and humiliation, whilst the ignorant one thinks that it is nobility.”
