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

ثلاثٌ مَن كُنَّ فيه ذاقَ طَعْمَ الإيمانِ: مَن كانَ لا شي‏ءَ أحبُّ إلَيهِ مِن‏اللَّهِ ورسولِهِ، ومن كان لَأنْ يُحرقَ بالنّار أحبَّ إليهِ مِن أنْ يَرْتَدَّ عن دِينِهِ، ومن كانَ يُحبُّ للَّهِ ويُبغضُ للَّهِ.

'Three qualities which, when present in a person, enable him to savour the taste of faith: that nothing is more beloved to him than Allah and His Messenger, that to be burned in the Fire is more beloved to him than to denounce his religion, and that he loves for the sake of Allah and hates for the sake of Allah.'
