The rewards of those who exercise patience will be doubled

In the Name of Allah, the Most Beneficent, the Most Merciful.

Allaah tabaarak ta wa ta’aala says:

"These will be given their reward twice over, because they are patient, and repel evil with good, and spend (in charity) out of what We have provided for them." [Soorah al-Qasas 28:54] 

a) Narrated Abu Burdah's father: Allah's Messenger [sal-Allahu 'alayhi wa sallam] said, "Any man who has a slave-girl whom he educates properly, teaches good manners, manumits and marries her, will get a double reward. And if any man of the people of the Scriptures (Jews and Christians) believes in his own Prophet and then believes in me (Muhammad [sal-Allahu 'alayhi wa sallam]) too, he will (also) get a double reward. And any slave who fulfills his duty to his master and to his Lord (Allah), will (also) get a double reward." [Sahih Al-Bukhari, 7/5083 (O.P.20)]

In the same way that when traveling we ensure that our baggage does not exceed the airline weight limitation because of the fear of being penalised, 
we should also ensure that we do not carry excess baggage into the journey of Hereafter.
The correct weight is achieved through prayer, forgiving others, letting go of sin & other negative issues that we have held onto far too long, 
cleansing our hearts from jealousy, envy, hatred & evil thoughts, choosing the correct friends, assisting others, 
improving our character & abstaining from foul language & oppression. 
It is important to do a weight check before arriving at the ultimate scale of justice.
