"As for anyone who keeps secret a good deed, Allah will sooner or later reveal a good reputation for him. As for him who keeps secret an evil, Allah will sooner or later reveal an ill reputation for him." 179
This category of showiness stands for pretending faith and concealing disbelief. It is hypocrisy, which is the most serious and the gravest danger on Muslims.
This category stands for practicing acts of worship openly before people so as to show them, while the same acts of worship are neglected in seclusions. As example of this category is to offer prayers openly, show the signs of fasting, prolong the gestures of the prayer, recite in a distinguishable way, frequent to the mosques, witness the collective prayers incessantly, and practice similar acts pretentiously. The showy, in this case, is considered as more sinful than the neglector of worship because he does so out of his disregarding God and trying to deceive people.
Under this category lie the pretence of being pious, having the beard unshaved, branding the forehead as a sign of frequent prostration, dressing hard clothes, and the like false appearances of ascetics.
Under this category lie the false declamation of wisdom, pretence of enjoining good and forbidding evil, and mentioning the divine reward and punishment.
(1) Fondness of high rank is the most important incentive of showiness.
