"Those who were obstructing mankind from Lord Allah’s path, and trying to make It crooked and were disbelievers with the Hereafter".
The hypocrites and their blind followers Mushriks are the wrongdoers. They are the Fujjar Mujirims who neither utilize Adhikr nor give It to others. By doing so they are destroying none except themselves, but they perceive it not as explained in verse 6: 26. The Fujjar are having an evil concept about Lord, so they will have evil consequences, Lord's wrath and curse have happened upon them and Hell is kept preserved for them as told in verse 48: 6. They are the disbelievers, wrongdoers and transgressors respectively explained in verses 5: 44, 45 and 47. It is told in verses 11: 17-19 that from the Fujjar groups whoever disbelieves with Adhikr which is the Evidence, Mercy, Guide, Truth, and Witness, then Fire is promised to him; so you don’t need to doubt about It, but most of the people don’t believe. And who is more unjust than the one who forges a lie about Lord? Such will be presented before their Lord, and the witnesses will say: “These are the ones who were lying against their Lord”, know that the curse of the Lord is upon the wrongdoers who are obstructing people from Adhikr and seek to make It crooked, and they are disbelieving with the Hereafter". The Vile valley of Hell is kept prepared for the Mushriks who don't believe in the Hereafter as told in verses 41: 6-7. See explanation 2: 79; 4: 144, and 6: 115-117.
