Hawzah News Agency – The merciful prophet of Islam (pbuh) says:

أكثِروا مِن ذِكرِ هادِمِ اللَّذّاتِ، فقيلَ: يا رسولَ اللَّهِ، فما هادِمُ اللَّذّاتِ؟ قالَ: المَوتُ، فإنّ أكيَسَ المؤمنينَ أكثَرُهُم ذِكراً للمَوتِ، وأشَدُّهُم لَهُ استِعداداً.

'Increase the remembrance of the demolisher of desires.' He was asked, 'O Messenger of Allah, what is the demolisher of desires?' He said, 'Death, for the most sagacious of believers are those who remember death the most and are the most prepared for it.'
