وَإِمَّا نُرِيَنَّكَ بَعْضَ ٱلَّذِى نَعِدُهُمْ أَوْ نَتَوَفَّيَنَّكَ فَإِلَيْنَا مَرْجِعُهُمْ ثُمَّ ٱللَّهُ شَهِيدٌ عَلَىٰ مَا يَفْعَلُونَ
Whether We let thee (O Muhammad) behold something of that which We promise them or (whether We) cause thee to die, still unto Us is their return, and Allah, moreover, is Witness over what they do.

Fasting
Chapter: Can one select some special days (for observing Saum (fast))?
Narrated Alqama:
I asked `Aisha "Did Allah s Apostle, use to choose some special days (for fasting)?" She replied, "No, but he used to be regular (constant) (in his service of worshipping). Who amongst you can endure what Allah's Messenger (ﷺ) used to endure?"
