Dhambi huzuia uoni wa moyo, huufifisha nuru yake, na kuziba njia zote za kuongozwa kwake kwa uongofu sahihi. Imam Malik, Allah amridhie, alipoona dalili za elimu ya ajabu kwa Imam Shafi'i, alimwambia: "Naona kwamba Allah ~ amekuwekea nuru, basi usiizime kwa giza la kumwasi Yeye (kwa kufanya dhambi)." Mtu anapoendelea kufanya madhambi, nuru ya asili ambayo Allah ~ aliitia moyoni mwake hupungua mfululizo, kwani giza la dhambi huchukua nafasi, hadi lifunike moyo mzima na kuutupa katika ulimwengu wa giza; ulimwengu wa kujiangamiza. Giza hili huenea katika viungo vya mwili hadi kufikia uso, likiugeuza kuwa umbo lenye huzuni na kukata tamaa. Athari hii pia huhamia Maisha ya Baada ya Kifo, na kuongeza giza la kaburi. Mtume ﷺ amesema: "Makaburi haya yamejaa giza juu ya watu wake, lakini Allah huwaangazia kwa sala yangu juu yao." Siku ya Kiyama, watu wote watakusanywa, nyuso zao zikiwa zimeinuliwa juu na kuonekana wazi na kila mtu. Nyuso za wenye dhambi zitakuwa nyeusi, kama mkaa. Ni adhabu ambayo uzito wake hauwezi kulinganishwa na tamaa zote za dunia; hivyo ni lazima mtu awe na subira duniani.

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.
