Hawzah News Agency – The merciful prophet of Islam, peace be upon him and his household says:

ثلاثةٌ مَن كُنَّ فيهِ يَسْتَكمِلُ إيمانُهُ:  رجُلٌ لا يَخافُ في اللَّهِ لَوْمةَ لائمٍ، ولا يُرائي بشَي‏ءٍ مِن عَمَلِهِ، وإذا عَرَضَ علَيهِ أمْرانِ أحدُهُما للدُّنيا والآخَرُ للآخِرَةِ، اخْتارَ أمرَ الآخِرَةِ علَى الدُّنيا.

'Three qualities, when present in an individual, will complete his faith: a man who does not fear the reproach of an admonisher for the sake of Allah, who never shows off in any of his actions, and who when faced with two matters, one for this world and the other for the Hereafter, he chooses the matter of the Hereafter over the world.'
