[Machine] About the Prophet Muhammad ﷺ , he said, "Do not start the month by a day or two unless it coincides with your fasting. If one of you sees the new moon, then fast accordingly, and if it is covered from you, complete thirty days of Sha'ban (the month before Ramadan) and then fast. This narration is reported from Umar ibn al-Khattab, Abdullah ibn Abbas, Hudhayfah ibn al-Yaman, Talq ibn Ali, and others from the Prophet Muhammad ﷺ ."
عَنِ النَّبِيِّ ﷺ قَالَ لَا تَقَدَّمُوا الشَّهْرَ بِالْيَوْمِ وَالْيَوْمَيْنِ إِلَّا أَنْ يُوَافِقَ ذَلِكَ صَوْمًا كَانَ يَصُومُهُ أَحَدُكُمْ صُومُوا لِرُؤْيَتِهِ وَأَفْطِرُوا لِرُؤْيَتِهِ فَإِنْ غُمَّ عَلَيْكُمْ فَعُدُّوا ثَلَاثِينَ ثُمَّ أَفْطِرُوا وَرُوِيَ عَنْ عُمَرَ بْنِ الْخَطَّابِ وَعَبْدِ اللهِ بْنِ الْعَبَّاسِ وَحُذَيْفَةَ بْنِ الْيَمَانِ وَطَلْقِ بْنِ عَلِيٍّ وَغَيْرِهِمْ عَنِ النَّبِيِّ ﷺ
