11ـ أَحْمَدُ بْنُ إِدْرِيسَ عَنْ مُحَمَّدِ بْنِ أَحْمَدَ عَنْ يَعْقُوبَ بْنِ يَزِيدَ عَنْ مُحَمَّدِ بْنِ مُرَازِمٍ عَنْ أَبِيهِ عَنْ أَبِي عَبْدِ الله (عَلَيْهِ السَّلاَم) قَالَ إِذَا تَطَوَّقَ الْهِلالُ فَهُوَ لِلَيْلَتَيْنِ وَإِذَا رَأَيْتَ ظِلَّ رَأْسِكَ فِيهِ فَهُوَ لِثَلاثِ لَيَالٍ.

Ahmad ibn Idris Muhammad ibn Ahmad from Ya’qub ibn Yazid from Muhammad ibn Murazim from his father who has said the following: “Abu ‘Abd Allah عليه السلام, has said that if the crescent forms a crown around it, then it is two nights old and if you can see the shadow of your head it is three nights old.’”
