Mishkat al-Masabih #2548
The Rites of Pilgrimage
The Arabic includes the chain of narration (sanad) and the collector's commentary; the English translation shows the Prophet's words only.
وَعَن وَبرةَ قَالَ: سَأَلْتُ ابْنَ عُمَرَ: مَتَى أَرْمِي الْجِمَارَ؟ قَالَ: إِذَا رَمَى إِمَامُكَ فَارْمِهِ فَأَعَدْتُ عَلَيْهِ الْمَسْأَلَةَ. فَقَالَ: كُنَّا نَتَحَيَّنُ فَإِذَا زَالَتِ الشَّمْسُ رمينَا. رَوَاهُ البُخَارِيّ
Wabara said he asked Ibn ‘Umar when he should throw pebbles at the jamras, to which he replied, “Throw them when your imam does so.” He repeated the question and received the reply, “We used to wait for the proper time, and when the sun passed the meridian we threw them.”
Bukhari transmitted it.
