It was narrated that Abu Hurairah said: “The Messenger of Allah forbade anticipating the fast by fasting one day before sighting (of the crescent).”
حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا حَفْصُ بْنُ غِيَاثٍ، عَنْ عَبْدِ اللَّهِ بْنِ سَعِيدٍ، عَنْ جَدِّهِ، عَنْ أَبِي هُرَيْرَةَ، قَالَ نَهَى رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ عَنْ تَعْجِيلِ صَوْمِ يَوْمٍ قَبْلَ الرُّؤْيَةِ .
