Patience is extremely important in Islam. In the early period of Prophethood, the verses revealed by God to the Messenger were:

يَا أَيُّهَا الْمُدَّثِّرُ، قُمْ فَأَنْذِرْ، وَرَبَّكَ فَكَبِّرْ، وَثِيَابَكَ فَطَهِّرْ،  وَالرُّجْزَ فَاهْجُرْ، وَلَا تَمْنُنْ تَسْتَكْثِرُ، وَلِرَبِّكَ فَاصْبِرْ  

(74:1-7)

The Prophet was commanded to warn people about reform their lives and morals in this world. In the end the Quran says, Keep patience for the sake of God. There are thorns around you, or people who provoke you and speak against you. You must avoid them all. You must have patience against them. You must not act against them. Patience means to remain involved in your mission by avoiding the unpleasant elements. The entire Quran is full of this. There is a verse about patience and not about any other act. It says that patience has the greatest reward: إِنَّمَا يُوَفَّى الصَّابِرُونَ أَجْرَهُمْ بِغَيْرِ حِسَابٍ. (39:10)

There is unlimited reward for those who have patience. There is no reward for any other act. Why is this so? Because they accepted God's creation plan. God has given freedom to every person based on His creation plan. They behave in different ways due to this freedom. If you don’t react to them, remained patient over it and accepted God's plan, you will be rewarded.  There is a great glad tiding: if you accept God's creation plan you will be rewarded without measure.إِنَّمَا يُوَفَّى الصَّابِرُونَ أَجْرَهُمْ بِغَيْرِ حِسَابٍ. It is indeed great in the eyes of God to accept God's creation plan.
