Every sin you commit intentionally backfires on you mentally, physically, spiritually.

You lose your connection with Allah.

You wonder where the shine of your face has disappeared.

The Prophet ﷺ said, 'Verily, when the servant commits a sin, a black mark appears upon his heart. If he abandons the sin, seeks forgiveness, and repents, then his heart will be polished. If he returns to the sin, the blackness will be increased until it overcomes his heart. It is the covering that Allah has mentioned: No, rather a covering is over their hearts from what they have earned

An-Nu‘mân b. Basheer narrates: The Prophet ﷺ said: 'The one who abides by Allah’s boundaries and the one who falls into them are comparable to people who draw lots on a bout. Some get the top, while others get the bottom. When those on the bottom get thirsty, they pass by those above them and say: ‘We should poke holes in our section and not bother those above us.’ If they let them do what they want, they will all perish, but if they hold their hands back, they will prosper, and they will all prosper together.' [Authentic: Narrated by al-Bukhari (2493)]

I heard the Messenger of Allah ﷺ say…' (and he mentioned the hadith).

Abdullah b. Mas‘ood narrates: The Messenger of Allah ﷺ said: 'There was not a single prophet whom Allah sent before me except that he had disciples and companions among his nation who hold to his tradition and follow his command. Then after them come generations who say what they do not do, and do what they are not commanded to do. Whoever fights against them with his hand is then a believer, and whoever fights against them with his tongue is then a believer, and whoever fights against them with his heard it then a believer. But after that, there is not a mustard seed of faith left.' [Authentic: Narrated by Muslim (50)]

Qays b. Abu Hâzim narrates: Abu Bakr stood up, praised Allah and extolled him, and then said: 'O People! You all recite this ayah: O believers! You are accountable only for yourselves. It will not harm you if someone chooses to deviate—as long as you are ˹rightly˺ guided. [5:105] 'We certainly heard the Messenger of Allah ﷺ say: ‘If the people see something objectionable that they do not change, then Allah is about to include them all in His punishment.’' [Authentic: Narrated by Abu Dawud (4338), and at-Tirmidhi (2168), and Ibn Mâjah (4005), and an-Nasâ’i in al-Kubra (11092)]

Then the murderer will come and say: ‘I murdered for this?!’ Then the one who cut ties will come and say: ‘I cut ties with my family for this?!’ Then the thief will come and say: ‘My hand was cut for this?!’ They will then leave it and not take anything from it.' [Authentic: Narrated by Muslim (1013)]

‘Ubâdah b. as-Sâmit narrates: The Messenger of Allah (saws) took an oath from us just as he did from the women: to not associate anything as a partner with Allah; to not steal; to not fornicate; to not kill our children; and to not incite dissension among one another. [He said]: 'Whoever fulfills it among has his reward with Allah. Whoever among you commits a crime and is penalized for it, then it is his expiation, and whomever Allah conceals, then his matter is up to Allah; if He wills, He will punish him, and if He wills, he will forgive him.' [Authentic: Narrated by Muslim (1809:43)]

Jareer b. Abdullah narrates that the Messenger of Allah (saws) said: We were sitting with the Messenger of Allah at the start of the day when there came to him some people who were barefoot, naked, and wearing striped woolen clothes or cloaks, with swords hanging from their necks. Most of them were from Mudhar - rather, all of them were from Mudhar. The face of the Messenger of Allah (saws) changed when he saw they were impoverished. So he entered [his house], and then came out. He ordered Bilal, who then made the call [to prayer] and the call of the establishment [of the prayer].

Abdullah b. Mas‘ood said: 'Allah cursed the tattoo artist and those who get tattoos, the women who have hair removed from their faces, and those who wedge a space between their teeth for beauty, changing the creation of Allah.'
