In the Hadith it says in Ramadan devils are chained. How are people then tempted to do evil in this month?
Yes, there is that Hadith but reality tells us that there are some people who sin and violate the sanctity of the blessed month. However, there is no contradiction between the Hadith and this reality as according to commentators of Hadith, what is meant is that Shaytaan (Satan) has no control over those people who are righteous and obedient to Allah’s ordinances. Thus Ramadan is a perfect environment for religious commitment and spiritual purity, but this very special environment may be exposed to sinful pollution because of recklessness.
