151. hadíth
وَ رَوَى مُحَمَّدُ بْنُ مُرَازِمٍ عَنْ أَبِيهِ عَنْ أَبِي عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ قَالَ: «إِذَا تَطَوَّقَ اَلْهِلاَلُ فَهُوَ لِلَيْلَتَيْنِ وَ إِذَا رَأَيْتَ ظِلَّ رَأْسِكَ فِيهِ فَهُوَ لِثَلاَثِ لَيَالٍ»
Muhammad ibn Murazim narrated from his father, from Abu Abdullah (a.s), who said: "If the crescent appears surrounded by a halo, it is for two nights. If you can see the shadow of your head in it, it is for three nights."
