What can I do to repent for almost 3 years of disobedience to Allah?

Allah is Most Gracious and Most Merciful. He says in the Noble Qur'aan, 'Oh%0D%0AMy Slaves! Do not despair. Verily Allah will forgive all sins.'%0D%0A%0D%0AIn one Hadith, Rasulullah (Sallallaahu Alayhi Wasallam) is reported to have%0D%0Asaid, 'If a person has sins equivalent to the foams of the sea and pebbles%0D%0Aon a desert, Allah's mercy is so encompassing that He will forgive every%0D%0Asin.' In another narration, it is mentioned that Allah will speak secretly%0D%0Ato one of His slaves on the day of Qiyaamat and remind him of all his sins.%0D%0AAfter the person will confess his sins, Allah will say to him, 'I concealed%0D%0Ayour faults in the world, today too, I will conceal your faults. Go in%0D%0AJannah, I have forgiven you.'%0D%0A%0D%0AThe above mentioned are few of many Ahaadith explaining the extent of%0D%0AAllah's Mercy. However, Allah says, 'Verily Allah will not forgive a person%0D%0Awho ascribe partners (commit Shirk) with Him.' The only sin that is%0D%0Aunforgivable is Kufr (disbelief) and Shirk (ascribing partners). Accepting%0D%0AIslam is the only atonement for the sin of Kufr and Shirk.%0D%0A%0D%0AIf one fulfils the conditions of repentance, i.e. regret and make firm%0D%0Aintention to reform, then surely Allah Ta'ala is Tawwaab (Most Forgiving)%0D%0A%0D%0AAnd Allah Ta%E3la Knows Best.%0D%0A%0D%0AWas salaam%0D%0A%0D%0AMufti Ebrahim Desai%0D%0AFATWA DEPT.%0D%0A
