One of their methods was that they used to mock the verses of the Qur’ān in order to both disturb their sacredness and hurt the Muslims. This verse states the indecent reaction of the hypocrites at the time of the revelation of a Surah of the Qur’ān. Whenever a Surah was revealed, some of them mockingly asked some others whether that Surah increased in belief of either of them. By that manner, they wanted to mock the Muslims among themselves.

After narrating this meaning, the Qur’ān gives them a suitable answer, which is recited in the next verse. Whenever a Surah of the Qur’ān was sent down, there were created two reactions in the believers and two other reactions in the hypocrites. Every couple of those reactions were just opposite to each other. The reaction of the believers before the revelation of a Surah of the Qur’ān was two things: The first was that it increased in the belief of them and made their Faith firm.

This statement indicates that belief can be both decreased and increased, and the revelation of the Qur’ān causes the belief to be increased in the receptive believing hearts. The second was that it made them happy. When they heard the verses of the Qur’ān, and they were aware of the great rewards which were mentioned in them for the believers, they rejoiced and they became hopeful that they would be included in the favours of Allah.

“And as for those in whose hearts is a sickness, it (only) adds filth to their filth, and they die while they are infidels.”*** If a corpse falls inside a pool, whatever much rain it rains upon it, it will become more malodorous. This bad smell is not because of the rain, but it is because of that corpse.

When there is the mood of obstinacy and haughtiness in a person, it causes that, by the revelation of the verses of the Qur’ān, those in whose hearts is disease will become more haughty, and will show a more amount of obstinacy, bigotry and enmity from themselves. This status is a kind of sickness in them like the sicknesses of the body. If we do not think of a remedy for it, it will expand so much so that may it destroy the person.
