3. Celebrate the Praises of thy Lord and pray for His Forgiveness: for He is Oft-Returning (in Grace and Mercy).

Notes (Tafseer)

6293. Every man should humble himself before Allah, confess his human frailties, and seek Allah's grace;-attributing any success that he gets in his work, not to his own merits, but to the goodness and mercy of Allah. But the Prophet of Allah had also another duty and privilege,-to pray for grace and forgiveness for his people in case any of them had exulted in their victory or done anything that they should not have done.
