Reminder—who is sure that he/she will wake up tomorrow?!
Allaah (The Most High) said:
ٱللَّهُ يَتَوَفَّى ٱلۡأَنفُسَ حِينَ مَوۡتِهَا وَٱلَّتِى لَمۡ تَمُتۡ فِى مَنَامِهَاۖ فَيُمۡسِكُ ٱلَّتِى قَضَىٰ عَلَيۡہَا ٱلۡمَوۡتَ وَيُرۡسِلُ ٱلۡأُخۡرَىٰٓ إِلَىٰٓ
أَجَلٍ۬ مُّسَمًّىۚ إِنَّ فِى ذَٲلِكَ لَأَيَـٰتٍ۬ لِّقَوۡمٍ۬ يَتَفَكَّرُونَ
”It is Allah Who takes away the souls at the time of their death, and those that die not during their sleep. He keeps those (souls) for which He has ordained death and sends the rest for a term appointed. Verily, in this are signs for a people who think deeply.” [39:42]
