“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 «رُبَّ صَائِمٍ حَظُّهُ مِنْ صِيَامِهِ الْجُوعُ وَرُبَّ قَائِمٍ حَظُّهُ مِنْ قِيَامِهِ السَّهَرُ»
