THE MEANING OF ORIGINAL SIN ACCORDING TO ISLAM

What is the meaning of original sin? who is the cause of the original sin?Reading from Sahih Al Bukhari volume 8 Book 77 Number 611 it was Allah who caused adam to sin because it was destined for him to sin. Muslim argue with the christian about original sin but their book revealed Allah destined him to sin and therefore they were sent away from paradise for sin he was destined for.

 'The Prophet (ﷺ) said, "Adam and Moses argued with each other. Moses said to Adam. 'O Adam! You are our father who disappointed us and turned us out of Paradise.' Then Adam said to him, 'O Moses! Allah favored you with His talk (talked to you directly) and He wrote (the Torah) for you with His Own Hand. Do you blame me for action which Allah had written in my fate forty years before my creation?' So Adam confuted Moses, Adam confuted Moses," the Prophet (ﷺ) added, repeating the Statement three times.'

حَدَّثَنَا عَلِيُّ بْنُ عَبْدِ اللَّهِ، حَدَّثَنَا سُفْيَانُ، قَالَ حَفِظْنَاهُ مِنْ عَمْرٍو عَنْ طَاوُسٍ، سَمِعْتُ أَبَا هُرَيْرَةَ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ ‏ "‏ احْتَجَّ آدَمُ وَمُوسَى، فَقَالَ لَهُ مُوسَى يَا آدَمُ أَنْتَ أَبُونَا خَيَّبْتَنَا وَأَخْرَجْتَنَا مِنَ الْجَنَّةِ‏.‏ قَالَ لَهُ آدَمُ يَا مُوسَى اصْطَفَاكَ اللَّهُ بِكَلاَمِهِ، وَخَطَّ لَكَ بِيَدِهِ، أَتَلُومُنِي عَلَى أَمْرٍ قَدَّرَ اللَّهُ عَلَىَّ قَبْلَ أَنْ يَخْلُقَنِي بِأَرْبَعِينَ سَنَةً‏.‏ فَحَجَّ آدَمُ مُوسَى، فَحَجَّ آدَمُ مُوسَى ‏"‏ ثَلاَثًا‏.‏ قَالَ سُفْيَانُ حَدَّثَنَا أَبُو الزِّنَادِ، عَنِ الأَعْرَجِ، عَنْ أَبِي هُرَيْرَةَ، عَنِ النَّبِيِّ صلى الله عليه وسلم مِثْلَهُ‏.‏
