Almuntakhab Fi Tafsir Alquran Alkarim

Therefore, be patient O Muhammad and be unwearied in the face of difficulties and hindrances, and quietly await the course of events; the promise of Allah is the truth personified. Let not their disdainful attitude and their unsettled allegiance and belief influence your firm mind and your firm thoughts nor should you let them disturb or discompose your peace of mind

Tafseer Tafheem-ul-Quran by Syed Abu-al-A'la Maududi

(30:60) Therefore, (O Prophet), have patience. Surely Allah's promise is true. *84 Let those who lack certainty not cause you to be unsteady. *85

*84) The allusion is to the promise made in verse 47 above. There, AIIah has mentioned His way of taking vengeance on those criminals who denied and resisted and ridiculed the clear Signs brought by the Messengers of AIIah stubbornly, and of helping the believers.
*85) That is, "Let not the enemies find you so weak as to suppress you by their uproar, nor to cow you by their campaign of slander-mongering, nor to dishearten you by their jesting, taunts and derision, nor frighten you by their threats, show of power and persecution, nor allure you by offering baits, nor make you effect a compromise with them on the basis of their appeals in the name of national interests. Instead of this, they should find you so sagacious in the awareness of your objective, so firm in faith and conviction, so resolute in determination, and so strong in character that they should neither be able to cow you by threats, nor purchase you, nor lure you away by temptation, nor strike any bargain with you in the matter of the Faith. T. his whole theme has been compressed in a short sentence by AIIah, saying: "Let not those who lack faith find you light." Now this is borne out by the firm evidence of history that the Holy Prophet proved to be as invincible and indomitable as AIIah wanted His Last Prophet to be. Anyone who tried his strength with him in any field and sphere was routed, and eventually the Holy Prophet succeeded in bringing about the desired revolution in spite of every kind of opposition and resistance put up by the whole of polytheistic and unbelieving Arabia.
