'I have sighted the crescent.' He said: 'Do you bear witness that there is none worthy of worship except Allah, and that Muhammad is His slave and Messenger?' He said: 'Yes.' So the Prophet gave the call saying: 'Fast."'  

جَاءَ أَعْرَابِيٌّ إِلَى النَّبِيِّ ﷺ فَقَالَ رَأَيْتُ الْهِلاَلَ فَقَالَ أَتَشْهَدُ أَنْ لاَ إِلَهَ إِلاَّ اللَّهُ وَأَنَّ مُحَمَّدًا عَبْدُهُ وَرَسُولُهُ قَالَ نَعَمْ فَنَادَى النَّبِيُّ ﷺ أَنْ صُومُوا  

“A Bedouin came to the Prophet ﷺ and said: ‘I have seen the new crescent tonight.’ He said: ‘Do you bear witness that none has the right to be worshipped but Allah and that Muhammad is the Messenger of Allah ﷺ?’ He said: ‘Yes.’ He said: ‘Get up, O Bilal, and announce to the people that they should fast tomorrow.’” Abu 'Ali said: "This is how it was narrated from Walid bin Abu Thawr and Hasan bin 'Ali. It was also narrated from Hammad bin Salamah, but he did not mention Ibn 'Abbas. He said: 'And he announced that they should perform the prayer and that they should fast.'"  

جَاءَ أَعْرَابِيٌّ إِلَى النَّبِيِّ ﷺ فَقَالَ أَبْصَرْتُ الْهِلاَلَ اللَّيْلَةَ فَقَالَ أَتَشْهَدُ أَنْ لاَ إِلَهَ إِلاَّ اللَّهُ وَأَنَّ مُحَمَّدًا رَسُولُ اللَّهِ قَالَ نَعَمْ قَالَ قُمْ يَا بِلاَلُ فَأَذِّنْ فِي النَّاسِ أَنْ يَصُومُوا غَدًا  

A bedouin came to the Prophet ﷺ and said: I have sighted the moon. Al-Hasan added in his version: that is, of Ramadan. He asked: Do you testify that there is no god but Allah? He replied: Yes.

He said: Bilal, announce to the people that they must fast tomorrow. (Using translation from Abū Dāʾūd 2340)

The Messenger of Allah asked him, "Do you testify that there is no deity worthy of worship except Allah and that Muhammad is the Messenger of Allah?" The man replied, "Yes." The Messenger of Allah then said, "Proclaim to the people to begin fasting." This narration was reported by Al-Fadl ibn Musa from Sufyan Ath-Thawri.  

جَاءَ رَجُلٌ أَعْرَابِيٌّ لَيْلَةَ هِلَالِ رَمَضَانَ فَقَالَ يَا رَسُولَ اللَّهِ إِنِّي قَدْ رَأَيْتُ الْهِلَالَ فَقَالَ «أَتَشْهَدُ أَنْ لَا إِلَهَ إِلَّا اللَّهُ وَتَشْهَدُ أَنَّ مُحَمَّدًا رَسُولُ اللَّهِ؟» قَالَ نَعَمْ قَالَ «فَنَادِ فِي النَّاسِ أَنْ يَصُومُوا» وَهَكَذَا رَوَاهُ الْفَضْلُ بْنُ مُوسَى عَنْ سُفْيَانَ الثَّوْرِيِّ

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
