M. H. Shakir, The Holy Quran; Arabic Text and English Translation; Foot-notes by M. H. Shakir (1974)
His Apostle when he calls you to that which gives you life; and know that Allah intervenes between man and his heart, and that to Him you shall be gathered.
25. And fear an affliction which may not smite those of you in particular who are unjust; and know that Allah is severe in requiting (evil).
26. And remember when you were few, deemed weak in the land, fearing lest people might carry you off by force, but He sheltered you and strengthened you with His aid and gave you of the good things that you may give thanks.
27. O you who believe! be not unfaithful to Allah and the Apostle, nor be unfaithful to your trusts while you know.
28. And know that your property and your children are a temptation, and that Allah is He with Whom there is a mighty reward.
29. O you who believe! If you are careful of (your duty to) Allah, He will grant you a distinction and do away with your evils and forgive you; and Allah is the Lord of mighty grace.
Muhammad could collect only a small band of 313 followers. The defence was made up of ill-equipped fighters, including young boys and old men. Instead of waiting for the attackers the Prophet decided to meet them at Badr, a little distance away from Medina. The fight was fast and furious and the Kafers were defeated. Ali made a name for himself for his bravery.
