This surah speaks about the honour of standing in battle array with believers in the company of the Prophet Muhammad (s) who taught his followers the highest chivalry and mercy towards the innocent.
This surah is thought to have come following the battle of Uhud. If you would like to read about this event to your children there is a chapter concerning the Battle of Uhud in The Light of Muhammad by Hajjah Amina Adil.
Discussion question: was it important for the believers to stand in solidarity with the Prophet (s) in battle? Does Allah (s) love those who stood by the Prophet (s)?
