“When you see the new crescent then fast, and when you see it then stop fasting. If it is cloudy then fast thirty days.” (Using translation from Ibn Mājah 1655)
قَالَ رَسُولُ اللهِ ﷺ إِذَا رَأَيْتُمُ الْهِلَالَ فَصُومُوا وَإِذَا رَأَيْتُمُوهُ فَأَفْطِرُوا فَإِنْ غُمَّ عَلَيْكُمْ فَصُومُوا ثَلَاثِينَ يَوْمًا
