[Machine] I heard Abu Al-Azhar say that Muawiyah stood at the monastery of Misr on the gate of Hims and said, "Indeed, fasting is on this day and this day, and we are advancing tomorrow." So, Malik bin Hubayrah stood up to him and said, "O Muawiyah, is this an opinion you have seen or something you heard from the Messenger of Allah ﷺ ?" He replied, "I heard the Messenger of Allah ﷺ say, 'Fast the month and keep it a secret.'"  

سَمِعْتُ أَبَا الْأَزْهَرِ يَقُولُ قَامَ مُعَاوِيَةُ بِدَيْرِ مِسْحَلٍ الَّذِي عَلَى بَابِ حِمْصٍ فَقَالَ أَلَا إِنَّ الصِّيَامَ يَوْمُ كَذَا وَكَذَا وَإِنَّا مُتَقَدِّمُونَ غَدًا فَقَامَ إِلَيْهِ مَالِكُ بْنُ هُبَيْرَةَ فَقَالَ يَا مُعَاوِيَةُ أَرَأْيٌ رَأَيْتَهُ أَمْ شَيْئًا سَمِعْتَهُ مِنْ رَسُولِ اللهِ ﷺ؟ فَقَالَ سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ «صُومُوا الشَّهْرَ وَسِرَّهُ»
