“There are people who fast and get nothing from their fast except hunger, and there are those who pray and get nothing from their prayer but a sleepless night.” (Using translation from Ibn Mājah 1690)
قَالَ رَسُولُ اللَّهِ ﷺ «كَمْ مِنْ صَائِمٍ لَيْسَ لَهُ مِنْ صِيَامِهِ إِلَّا الْجُوعُ وَكَمْ مِنْ قَائِمٍ لَيْسَ لَهُ مِنْ قِيَامِهِ إِلَّا السَّهَرُ»
