"Raja bin Haiwah narrated that Abu Umamah said: 'I came to the Messenger of Allah and said: Tel l me of something that I may take (learn) from you. He said: "Take to fasting, for there is nothing like it."' ' (Using translation from Nasāʾī 2220)

أَتَيْتُ رَسُولَ اللهِ ﷺ فَقُلْتُ مُرْنِي بِأَمْرٍ آخُذُهُ عَنْكَ قَالَ «عَلَيْكَ بِالصَّوْمِ فَإِنَّهُ لَا مِثْلَ لَهُ»
