罪恶会蒙蔽心的洞察力，熄灭它的光明，并阻断一切通往正道的途径。当伊玛目马立克（愿真主喜悦他）发现伊玛目沙斐仪身上显露出非凡的学识迹象时，他对他说："我看到真主已把光明投在你身上，所以不要用违抗祂的黑暗（即犯罪）将它熄灭。" 当一个人持续作恶时，真主投在他/她心中的原始光明就会不断减弱，罪恶的黑暗随之侵占，直到淹没整颗心，使其陷入黑暗的世界，即自我毁灭的世界。这种黑暗会蔓延至肢体，直至面容，使其变成一副阴沉、失望的模样。这种影响还会延续到后世，并加重坟墓中的黑暗。先知ﷺ说："这些坟墓充满了对其居住者的黑暗，但真主借着我为他们所做的祈祷，为他们照亮。" 在复活日，所有人都将被集合，面孔高高扬起，为所有人清楚地看见。罪人的脸将变得黝黑，如同木炭。这是一种无法与今世一切欲望相提并论的惩罚，因此人在今世必须有耐心。

Sins blind the heart ' s insight, blot out its light, and block all means towards its right guidance. When Imam Malik, may Allah be pleased with him, saw signs of remarkable knowledge in Imam Shafi'i, he told him: "I see that Allah ~ has cast a light upon you, so do not extinguish it with the darkness of disobedience to Him (by committing a misdeed)." When a person continues to do misdeeds, the original light, which Allah ~ had cast in his/her heart, continues to decrease, as the darkness of sins takes over, until it overwhelms the whole heart, and casts it in the world of darkness; the world of self-destruction. This darkness spreads in the limbs until it reaches the face, turning it into a gloomy disillusioned figure. This effect is also carried over to the Life After Death, and adds to the darkness of the grave. The Prophet ~ said: "These graves are filled with darkness, over its people, but Allah sheds light on them, with my prayer upon them." On the Day of Resurrection, all people would be gathered, with their faces raised high and clearly seen by everyone. The faces of sinners will be blackened, like charcoal. It is a punishment which is not equal in weight to all the worldly desires; so one must be patient in this world.
