Mukhtasar Bukhari (Abridged) 526 — Praying on mount or by gesture when

Narrated Ibn Umar (may Allah be pleased with them): When the Prophet (peace and blessings of Allah be upon him) returned from the Battle of Ahzab, he said to us: "No one should offer the Asr prayer except at Banu Qurayza." Some people were overtaken by the time of Asr on the way, so some of them said, "We will pray now, because the Prophet (peace and blessings of Allah be upon him) did not mean for us to miss the time of Asr." So they prayed. This was mentioned to the Prophet (peace and blessings of Allah be upon him), and he did not express any displeasure towards anyone.
