"Abu Umamah Al-Bahili narrated to me: 'I said: O Messenger of Allah, tell me of something by which Allah will benefic me. He said: Take to fasting, for there is nothing like it."' (Using translation from Nasāʾī 2221)

قُلْتُ يَا رَسُولَ اللهِ مُرْنِي بِأَمْرٍ يَنْفَعُنِي اللهُ بِهِ قَالَ «عَلَيْكَ بِالصِّيَامِ فَإِنَّهُ لَا مِثْلَ لَهُ»
