حَدَّثَنَا سُفْيَانُ عَنْ عَمْرٍو عَنْ مُحَمَّدِ بْنِ حُنَيْنٍ عَنِ ابْنِ عَبَّاسٍ عَجِبْتُ مِمَّنْ يَتَقَدَّمُ الشَّهْرَ وَقَدْ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ لَا تَصُومُوا حَتَّى تَرَوْهُ أَوْ قَالَ صُومُوا لِرُؤْيَتِهِ
مسند امام احمد بن حنبل · Hadith 1931
It was narrated from Ibn 'Abbas: I am surprised at those who anticipate the month when the Messenger of Allah (PBUH) said: "Do not fast until you see it" or he said "Fast when you see it."
