The Peak of Eloquence · Hadith 814 (#Passage #4)

وَاعْلَمُوا ـ عِبَادَ اللهِ ـ أَنَّ الْمُؤْمِنَ لاَ يُصْبِحُ وَلاَ يُمْسِي إلاَّ وَنَفْسُهُ ظَنُونٌ عِنْدَهُ، فَلاَ يَزَالُ زَارِياً عَلَيْهَا وَمُسْتَزِيْداً لَهَا، فَكُونُوا كَالسَّابِقِينَ قَبْلَكُمْ، وَالْمَاضِينَ أَمَامَكُمْ، قَوَّضُوا مِنَ الدُّنْيَا تَقْوِيضَ الرَّاحِلِ، وَطَوَوْهَا طَيَّ الْمَنَازلِ.

You should know, O creatures of Allāh, that a believer should be distrustful of his heart every morning and evening. He should always blame it (for shortcomings) and ask it to add to (its good acts). You should behave like those who have gone before you and the precedents in front of you. They left this world like a traveller and covered it as distance is covered.
