حَدَّثَنَا وَكِيعٌ حَدَّثَنَا شُعْبَةُ عَنْ عَمْرِو بْنِ مُرَّةَ عَنْ أَبِي الْبَخْتَرِيِّ قَالَ تَرَاءَيْنَا هِلَالَ رَمَضَانَ بِذَاتِ عِرْقٍ فَأَرْسَلْنَا رَجُلًا إِلَى ابْنِ عَبَّاسٍ فَسَأَلَهُ فَقَالَ إِنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ مَدَّهُ إِلَى رُؤْيَتِهِ
مسند امام احمد بن حنبل · Hadith 3208
It was narrated that Abul- Bakhtari said: We saw the new moon of Ramadan in Dhat Trq, so we sent a man to Ibn 'Abbas (RA) to ask him. He [Ibn 'Abbas (RA)] said: The Messenger of Allah (PBUH) said: "Allah causes it to appear for long enough that people can see it."
