*122). When, after the Battle of Uhud, the Makkan polytheists had travelled several stages of their journey, they began to tell themselves what a mistake they had made in allowing the opportunity to crush the power of Muhammad to slip out of their hands. At one place they halted and deliberated among themselves about launching a second attack on Madina. They failed, however, to muster sufficient courage and carried on to Makka. The Prophet, for his part, also realized that they might attack once again. On the second day of Uhud, therefore, he gathered the Muslims and urged them to pursue the unbelievers. Even though this was a highly critical moment, the true men of faith girded their loins and were prepared to lay down their lives at the behest of the Prophet. They accompanied him to Hamra' al-Asad, eight miles from Madina. The present verse refers to these dedicated men.
*123). These few verses were revealed almost one year after the Battle of Uhud. As they are connected with the events of the battle they were included in the present discourse.
