Recalling death awakens the heart. The Prophet ﷺ said: “Remember often the destroyer of pleasures — death.” (Tirmidhī — ḥasan). He said the wisest believers are “those who remember death most and are best prepared for what comes after it.” (Ibn Mājah — ḥasan).
العربية: عن أبي هريرة رضي الله عنه قال: قال رسول الله ﷺ: «أكثِروا ذكر هاذم اللذات» يعني الموت. (الترمذي). وقال: «أكيسُ المؤمنين أكثرهم للموت ذكرًا وأحسنهم لما بعده استعدادًا». (ابن ماجه).
Recall death daily — visit graves, attend funerals; it softens the heart and readies you for the Hereafter.
