Does falling into sin indicate that there is something wrong with one's 'aqeedah (belief system)?
When a person repents, he makes a vigorous start and says: "The Shaytaan is telling me to slow down", so he does more acts of worship. Then his enthusiasm cools down, and he says: "Allah does not burden any person beyond his scope", and his acts of worship become less until he goes back to the way he was.
My question: What advice can you give? Should he make a vigorous start, or take a gradual approach until it is established and then add more after a while, or should he follow the saying: "When your wind blows, then make the most of it"?.
A great reminder of Hereafter. We all have to Be aware of this great advice to keep remembering the day of Judgment.
