They were satisfied to be with those who stayed behind, and their hearts were sealed upon, then they don’t understand the aim of life.
During Messenger’s period even though the hypocrites were healthy and wealthy to do Jihad along with the Messenger, they asked excuses to sit with the weakling children, women and elders in their houses. Since today Adhikr—the Best Interpretation of Lord’s Book—is formed, the hypocrites are knowingly hiding It. By doing so Lord Allah has put a lid on their hearts and ears for not understanding Adhikr as explained in verses 6: 25-26. Hypocrites and their followers are compared to a dog that will not change its attitude as explained in verses 7: 175-176. These aimless transgressors are worst creatures since they are dumb for talking about the Splendid Book—Adhikr—and Its 40 names as explained in verses 8: 22 and 55. It is asked in verse 18: 57: Who is more unjust than the one who is reminded with Lord’s verses, then turns away from them and forgets what his hands have sent forth? indeed, We have placed a lid upon their hearts for not to understand It, and a cover upon their ear; and if you invite them to the Guidance, then they will never be guided forever”. See explanations 2: 18, 99; 6: 65 and 7: 179.
