(17) باب ذِكْرِ الاِخْتِلاَفِ عَلَى يَحْيَى بْنِ أَبِي كَثِيرٍ فِي خَبَرِ أَبِي سَلَمَةَ فِيهِ
It was narrated from Ibn 'Umar that the Prophet said:
"The month is like this," and (one of the narrators) Shubah did the same gesture as Jabalah had done, copying, Ibn 'Umar: "It is twenty-nine, as he gestured twice with all fingers of both hands, and putting down one of his fingers the third time."
