What is the authenticity of the story of the man who was prevented from entering Paradise due to a "straw" he took from its owner without his permission, and what is the ruling on similar actions, and do they prevent one from entering Paradise?

The story mentioned contains exaggeration, for the forgiveness of sins is not outweighed by the forgiveness of a straw, especially since it is a dream from which no action or ruling can be derived. It is incumbent upon a servant to be wary of the rights of other people, for these are among the ledgers that Allah does not forgive for their perpetrators. The Prophet, peace and blessings be upon him, warned against injustices to people, saying: "Whoever has wronged his brother, whether in his honor or anything else, let him seek his forgiveness today, before there will be no dinar or dirham. If he has good deeds, an amount corresponding to his wrongdoing will be taken from him. And if he has no good deeds, then some of the evil deeds of his companion will be taken and placed upon him." And what was mentioned about fearing what might cling to the hand is nothing but whispers from devils and excessive rigor in religion, unless the hand is snatching people's rights and money.
