The Fourth Principle: Multiplication of Good Deeds to The Exclution of the Evil Ones

 From the favours of the Gracious King is that His mercy precedes his anger, His forgiveness overcomess His punishment and that clemercy and pordoring are more beloved to Him than punishment and retribution. This is why He is happy with His slave´s righteous deeds and He mulitiplies them. He dislikes Evil deeds and He does not mulitiply them bur forgives them. Allah says,

If you lend to Allah a goodly lean (i.e. spend in Allah´s Cause) He will double it for you, and will forigve you. And Allah is Most Ready to appreciate and to reward. Most forbearing. (Surah At-Taghabun: 17)

The least number of times good deeds are multiplied is ten:

Whoever brings a good deeds (Islamic Monotheism and deeds of abedience to Allah and His Messenger salla alayhi wa sallam shall have ten times the like thereof to his credit. (Surah Al-An´am: 160)

As for evil deeds, its reward is the like of it. Allah the Exalted says,

and whoever brings and evil deeds (polytheism, disbelief, hypocrisy, and deeds of disbelienve to Allah and His Messenger salla alayhi wa sallam) shall have only the recompense of the like thereof, and they will not be wornged. (Surah al-An´am: 160)

The Messenger of Allah salla alayhi wa sallam said, (part of what he related form his Lord):

Your Lord is Merciful. Whoever intended to do good, but did not do it. One good deed was recorded for him, and he who intended to do good and also did it. (Between) ten to seven hundrede good deeds were recorded for him. And whoever intended evil, but did not commit it, one good deed is recorded against him, but if he commited that, it was recorded as one against him or Allah blots it, whoever is destroyed (afterwards by Allah is perished.

The Prophet salla alayhi wa sallam also said,

Whoever does a good deed, there is (in store) for him ten times the like in reward and even more. And whoever commits an evil deed, his reward is similar to it or I forive it. Whoever commits error the like of the eart (in vastness) and he meet Me without associating any partner with Me, I will mett Him with the same (Castness) of pardon. He who draws vlose to Me by the span of a hand I draw close to him by the cubit, and he who draws close to me by the cubit I draw close to him by the span of the outstretched arm, and he who walks towards Me I rush towards him.

From Allah´s grave is that He multiplies good deeds up to seven hundrede folds and more.

The likeness of those who spend their wealth in the Way of Allah, is as the Likeness of a grain (of corn); it grows seven ears, and each ear has a hundrede grains. Allah gives mainfold increase to whom He pleases. And Allah is All-Sufficient for His creatures´ needs, All-knower (Surah Al-Baqarah: 261)
