2b] Does doing major sins prevent repentance and good deeds from being accepted?

2b]
Al-Tirmidhi (3540) narrated that Anas ibn Maalik (may Allaah be pleased with him) said: I heard the Messenger of Allaah (peace and blessings of Allaah be upon him) say: “Allaah, may He be blessed and exalted, said: ‘O son of Adam, so long as you call upon Me and ask of Me, I shall forgive you for what you have done, and I shallnot mind. O son of Adam, were your sins to reach the clouds of the sky and were you then to ask forgiveness of Me, I wouldforgive you and I would not mind.’” Classed as saheeh by al-Albaani in Saheeh al-Tirmidhi.
Ibn Maajah narrated that ‘Abd-Allaah ibn Mas’ood (may Allaah be pleased with him) said: The Messenger of Allaah (peace and blessings of Allaah be upon him) said: “The one who repents from sin is like one who did not sin.” Classed as hasan by al-Albaani in Saheeh Ibn Maajah.
These verses and ahaadeeth indicate that Allaah forgives all sins, no matter how great or how many, for the one who repents to Him.
So strive in worship and obedience, regret the negligence and sins of thepast, and note that Allaah has no need of His slaves yet despite that He rejoices in their repentance, and even turns their bad deeds intogood deeds.
We ask Allaah to help youto remember Him, give thanks to Him and worship Him properly.
And Allaah knows best.
