Read Qur’an: surahs, verses and hadiths

۞ قُلۡ يَٰعِبَادِيَ ٱلَّذِينَ أَسۡرَفُواْ عَلَىٰٓ أَنفُسِهِمۡ لَا تَقۡنَطُواْ مِن رَّحۡمَةِ ٱللَّهِۚ إِنَّ ٱللَّهَ يَغۡفِرُ ٱلذُّنُوبَ جَمِيعًاۚ إِنَّهُۥ هُوَ ٱلۡغَفُورُ ٱلرَّحِيمُ

Say [Allah says], “O My slaves who have transgressed against themselves, do not despair of Allah’s mercy, for indeed Allah forgives all sins[15]. He is indeed the All-Forgiving, the Most Merciful.

[15] It is for those who repent and correct themselves, no matter how big the sins are. The only unforgivable sin in Islam is dying in disbelief in Allah or associating others with Him. See 4:48. The Prophet (ﷺ) reports that Allah Almighty says, "O children of Adam! As long as you call upon Me, putting your hope in Me, I will forgive you for what you have done, and I will not mind. O children of Adam! If your sins were to reach the clouds of the sky and then you sought My forgiveness, I would forgive you. O children of Adam! If you were to come to Me with sins filling the whole world and then you came to Me without associating partners with Me, I would certainly match your sins with forgiveness." [At-Tirmidhi]

‘Abdullah ibn Busr (may Allah be pleased with him) reported that a man said: O Messenger of Allah, the legislations of Islam have become too much for me, so inform me of something to hold on to. He said: "Keep your tongue moist with the remembrance of Allah."
