Those to whom people [i.e., hypocrites] said, "Indeed, the people have gathered against you, so fear them." But it [merely] increased them in faith, and they said, "Sufficient for us is Allāh, and [He is] the best Disposer of affairs."1
Translation: Saheeh International (English)
1 The one entrusted and relied upon; sufficient to manage all matters.
Some of the idolaters said to them that the Quraysh, led by Abū Sufyān, had come together in great numbers to fight against them and to finish them off, warning them against meeting them. But their words and attempts to scare them only increased their reliance on Allah and their trust in His promise. So they went out to meet them, saying that Allah was enough for them and that He is the best Protector, while committing their lives to Him.
