Hawzah News Agency – The commander of the faithful, Imam Ali peace be upon him says:

ثلاثٌ مَن كُنَّ فيهِ فَقَد رُزِقَ خَيرَ الدُّنيا والآخِرَةِ، هُنَّ: الرِّضا بالقَضاءِ، والصّبرُ على‏ البَلاءِ، والشُّكْرُ في الرَّخاءِ.

'There are three things which if one possesses, they have been endowed with the good of this world and the Hereafter. They are: contentment with [Allah's] decree, patience in the face of tribulation, and thankfulness in times of ease.'
