156. hadíth
وَ سَأَلَهُ اَلْعِيصُ بْنُ اَلْقَاسِمِ: عَنِ اَلْهِلاَلِ إِذَا رَآهُ اَلْقَوْمُ جَمِيعاً فَاتَّفَقُوا عَلَى أَنَّهُ لِلَيْلَتَيْنِ أَ يَجُوزُ ذَلِكَ قَالَ «نَعَمْ».
Al-'Is ibn al-Qasim asked Imam (a.s) about a situation where a group of people all see the crescent and agree that it is for two nights. Imam (a.s) said: "Yes, it is permissible."
