[Machine] An Arab man came to the Prophet ﷺ on the night of the sighting of the moon of Ramadan and said, "O Messenger of Allah, I have seen the new moon." The Prophet asked him, "Do you bear witness that there is no god but Allah and that I am the Messenger of Allah?" He replied, "Yes." The Prophet then proclaimed, "Fast tomorrow." This narration has been reported by Abu Asim from Al-Thawri, with an unbroken chain of transmission. It has also been narrated by others from Al-Thawri through a disconnected chain of transmission.
جَاءَ أَعْرَابِيٌّ إِلَى النَّبِيِّ ﷺ لَيْلَةَ هِلَالِ رَمَضَانَ فَقَالَ يَا رَسُولَ اللهِ إِنِّي قَدْ رَأَيْتُ الْهِلَالَ فَقَالَ أَتَشْهَدُ أَنْ لَا إِلَهَ إِلَّا اللهُ وَأَنِّي رَسُولُ اللهِ قَالَ نَعَمْ قَالَ فَنَادَى أَنْ صُومُوا وَكَذَلِكَ رُوِيَ عَنْ أَبِي عَاصِمٍ عَنِ الثَّوْرِيِّ مَوْصُولًا وَرَوَاهُ غَيْرُهُمَا عَنِ الثَّوْرِيِّ مُرْسَلًا
