And let them not think - those who are bent on denying the truth - that they shall escape [God]: behold, they can never frustrate [His purpose]. 59 And prepare against them what force you can and horses tied at the frontier, to frighten thereby the enemy of Allah and your enemy and others besides them, whom you do not know (but) Allah knows them; and whatever thing you will spend in Allah's way, it will be paid back to you fully and you shall not be dealt with unjustly. 60 ۞ And if they incline unto peace, then thou mayest incline thereunto, and rely thou on Allah; verily He is the Hearer, the Knower. 61 And if they intend to deceive you-- then surely Allah is sufficient for you; He it is Who strengthened you with His help and with the believers 62 And united their hearts; had you spent all that is in the earth, you could not have united their hearts, but Allah united them; surely He is Mighty, Wise. 63 O Prophet! God is enough for thee and those of the believers who follow thee! 64
