Hadith 31-330

بِهذَا الإسناد عَنْ النَّبِي‏ صَلَّى اللهُ عَلَيْهِ وَآلِهِ قالَ: مَن كَفّ غَضَبِهِ كَفَّ اللَّه عَنْهُ عَذابه وَمَن حُسن خُلقِه بلغه اللَّه دَرَجَة الصائم الْقائِم.

According to the same documentation, the Prophet (S) said, “God will turn away His Punishment from whoever controls his wrath. God will raise whoever makes his temper good to the ranks of those who fast and stay up at night for worship.”
