“I am fasting.” ‘Uthman said: “I heard the Messenger of Allah ﷺ say: ‘Fasting is a shield against the Fire just like the shield of anyone of you against fighting.’” (Using translation from Ibn Mājah 1639)

سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ الصِّيَامُ جُنَّةٌ مِنَ النَّارِ كَجُنَّةِ أَحَدِكُمْ مِنَ الْقِتَالِ
