Ali 'Imran 3:121

<h2>The Battle of Uhud</h2><p>According to the majority of scholars, these Ayat are describing the battle of Uhud, as Ibn `Abbas, Al-Hasan, Qatadah, As-Suddi and others said. The battle of Uhud occurred on a Saturday, in the month of Shawwal on the third year of Hijrah. `Ikrimah said that Uhud occurred in the middle of the month of Shawwal, and Allah knows best.</p><h2>The Reason Behind the Battle of Uhud</h2><p>The idolators suffered many casualties among their noble men at the battle of Badr. The caravan that Abu Sufyan led (before Badr) returned safely to Makkah, prompting the remaining Makkan leaders and the children of those who were killed at Badr to demand from Abu Sufyan to, "Spend this money on fighting Muhammad!" Consequently, they spent the money from the caravan on warfare expenses and mobilized their forces including the Ahabish tribes (tribes living around the city). They gathered three thousand soldiers and marched until they camped near Uhud facing Al-Madinah. The Messenger of Allah ﷺ led the Friday prayer and when he finished with it, he performed the funeral prayer for a man from Bani An-Najjar called Malik bin `Amr. The Prophet then asked the Muslims for advice, if they should march …

And when thou settedst forth at daybreak from thy housefolk to assign to the believers their positions for the battle, Allah was Hearer, Knower.

Remember that morning Thou didst leave Thy household (early) to post the faithful at their stations for battle: And Allah heareth and knoweth all things:

And (remember) when you (Muhammad SAW) left your household in the morning to post the believers at their stations for the battle (of Uhud). And Allah is All-Hearer, All-Knower.

Remember when you left your home in the morning, to assign battle-positions for the believers. God is Hearing and Knowing.
