“We were with ‘Ammar on the day concerning which there was some doubt. A (roasted) sheep was brought and some of the people moved away. ‘Ammar said: ‘Whoever is fasting on this day has disobeyed Abu Qasim ﷺ.’”  

كُنَّا عِنْدَ عَمَّارٍ فِي الْيَوْمِ الَّذِي يُشَكُّ فِيهِ فَأُتِيَ بِشَاةٍ فَتَنَحَّى بَعْضُ الْقَوْمِ فَقَالَ عَمَّارٌ مَنْ صَامَ هَذَا الْيَوْمَ فَقَدْ عَصَى أَبَا الْقَاسِمِ ﷺ  

“The Messenger of Allah ﷺ forbade anticipating the fast by fasting one day before sighting (of the crescent).”  

نَهَى رَسُولُ اللَّهِ ﷺ عَنْ تَعْجِيلِ صَوْمِ يَوْمٍ قَبْلَ الرُّؤْيَةِ  

“The Messenger of Allah ﷺ used to say from the pulpit, before the month of Ramadan: ‘Fasting will begin on such and such a day, but we are going to start fasting earlier, so whoever wants to start fasting earlier (i.e., in Sha’ban), let him do so, and whoever wants to wait until Ramadan begins, let him do so.’”  

أَنَّهُ سَمِعَ مُعَاوِيَةَ بْنَ أَبِي سُفْيَانَ عَلَى الْمِنْبَرِ يَقُولُ كَانَ رَسُولُ اللَّهِ ﷺ يَقُولُ عَلَى الْمِنْبَرِ قَبْلَ شَهْرِ رَمَضَانَ الصِّيَامُ يَوْمَ كَذَا وَكَذَا وَنَحْنُ مُتَقَدِّمُونَ فَمَنْ شَاءَ فَلْيَتَقَدَّمْ وَمَنْ شَاءَ فَلْيَتَأَخَّرْ
