Abu Qalaba, 'Abdullah bin Zayd al-Jarmi عبد الله بن زيد بن عمرو · Jihad (Kitab Al-Jihad)

The Prophet (ﷺ) named our cavalry "the Cavalry of Allah," when we were struck with panic, and when panic overtook us, the Messenger of Allah (ﷺ) commanded us to be united, to have patience and perseverance; and to be so when we fought.
