Perhaps he wanted to try to do some good deeds that might outweigh the bad deeds he had done by producing music:
Hadith Qudsi 19:5: “The Prophet said that Allah commanded him to destroy all the musical instruments, idols, crosses and all the trappings of ignorance.” (The Hadith Qudsi, or holy Hadith, are those in which Muhammad transmits the words of Allah, although those words are not in the Qur’an.)
Muhammad also said:
(1) “Allah Mighty and Majestic sent me as a guidance and mercy to believers and commanded me to do away with musical instruments, flutes, strings, crucifixes, and the affair of the pre-Islamic period of ignorance.”
(2) “On the Day of Resurrection, Allah will pour molten lead into the ears of whoever sits listening to a songstress.”
(3) “Song makes hypocrisy grow in the heart as water does herbage.”
(4) “This community will experience the swallowing up of some people by the earth, metamorphosis of some into animals, and being rained upon with stones.” Someone asked, “When will this be, O Messenger of Allah?” and he said, “When songstresses and musical instruments appear and wine is held to be lawful.”
(5) “There will be peoples of my Community who will hold fornication, silk, wine, and musical instruments to be lawful ….” — ‘Umdat al-Salik r40.0
In looking for some good deeds he could do, he may have turned to texts like these, all from the Qur’an:
“And slay them wherever ye find them, and drive them out of the places whence they drove you out, for persecution is worse than slaughter…” — 2:191
“They long that ye should disbelieve even as they disbelieve, that ye may be upon a level (with them). So choose not friends from them till they forsake their homes in the way of Allah; if they turn back (to enmity) then take them and kill them wherever ye find them, and choose no friend nor helper from among them…” — 4:89
“Many are the Jinns and men we have made for Hell: They have hearts wherewith they understand not, eyes wherewith they see not, and ears wherewith they hear not. They are like cattle – nay more misguided: for they are heedless (of warning).” — 7:179
“Against them make ready your strength to the utmost of your power, including steeds of war, to strike terror into (the hearts of) the enemies, of Allah and your enemies…” — 8:60
“Then, when the sacred months have passed, slay the idolaters wherever ye find them, and take them (captive), and besiege them, and prepare for them each ambush. But if they repent and establish worship and pay the poor-due, then leave their way free. Lo! Allah is Forgiving, Merciful.” — 9:5
“Fight those who believe not in Allah nor the Last Day, nor hold that forbidden which hath been forbidden by Allah and His Messenger, nor acknowledge the religion of Truth, (even if they are) of the People of the Book, until they pay the Jizya with willing submission, and feel themselves subdued.” — 9:29
“Therefore, when ye meet the Unbelievers (in fight), smite at their necks; At length, when ye have thoroughly subdued them, bind a bond firmly (on them): thereafter (is the time for) either generosity or ransom: Until the war lays down its burdens…” — 47:4
“German musician trades guitar for jihad in Syria,” From AlBawaba, August 20:
The Violations Documenting Center in Syria has released images of a German rapper turned Muslim convert fighting the regime of  President Bashar Assad in Latakia, Syria.
Formerly known as ‘Deso Dogg‘, this German musician now goes by the name of “German Abu Talha”.Â
Abu Talha seems to be in high spirits as he splashes Syrian spring water around shouting “Alhumdilallah”.
After securing various strategic villages in the Latakia area, which is also the homeland of Assad, the rebels were forced out of the province by Syrian troops on Monday.fr
