60. So patiently persevere: for verily the promise of Allah is true: nor let those shake thy firmness who have (themselves) no certainty of faith.
3578. The Prophet of Allah does not slacken in his efforts or feel discouraged because the Unbelievers laugh at him or persecute him or even seem to succeed in blocking his Message. He has firm faith, and he knows that Allah will finally establish His Truth. He goes on in his divinely entrusted task, with patience and perseverance, which must win against the levity of his opponents, who have no faith or certainty at all to sustain them.
