Pray your Salaah like it's your last

عَنْ مُعَاوِيَةَ بْنِ قُرَّةَ قَالَ: قَالَ مُعَاذٌ لِابْنِهِ: يَا بُنَيَّ إِذَا صَلَّيْتَ صَلَاةً فَصَلِّ صَلَاةَ مُوَدِّعٍ لَا تَظُنُّ أَنَّكَ تَعُوْدُ إِلَيْهَا أَبَدًا ، وَاعْلَمْ يَا بُنَيَّ أَنَّ الْمُؤْمِنَ يَمُوْتُ بَيْنَ حَسْنَتَيْنِ: حَسَنَةً قَدَّمَهَا وَحَسَنَةً أَخَّرَهَا

It is reported from Mu’awiyah ibn Qurrah that Mu’adh ibn Jabal, may Allah have mercy on him, said to his son:

“O my son! When you pray, pray as if you are going to pass on, do not think you are ever going to come back to it. And know, O my son, that the believer dies between two good deeds: a good deed he has sent forwards, and a good deed he has deferred for later”.
