حَدَّثَنَا هَاشِمُ بْنُ الْقَاسِمِ ، حَدَّثَنَا شُعْبَةُ ، حَدَّثَنِي مُحَمَّدُ بْنُ زِيَادٍ ، قَالَ : سَمِعْتُ أَبَا هُرَيْرَةَ رَضِيَ اللهِ عَنْهُ، يَقُولُ : قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ، أَوْ قَالَ أَبُو الْقَاسِمِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ :" صُومُوا لِرُؤْيَتِهِ، وَأَفْطِرُوا لِرُؤْيَتِهِ، فَإِنْ غُمَّ عَلَيْكُمْ الشَّهْرُ، فَعُدُّوا ثَلَاثِينَ "

Hashim bin Al-Qasim told us, Shu’bah told us, Muhammad bin Ziyad told me, he said: I heard Abu Hurairah, may God be pleased with him, saying: He said: The Messenger of God, may God bless him and grant him peace, or Abu al-Qasim, may God bless him and grant him peace, said: “Fast when you see it, and break your fast when you see it. You have a month, so count thirty.”
