Those who wait [and watch] you. Then if you gain a victory from Allāh, they say, "Were we not with you?" But if the disbelievers have a success, they say [to them], "Did we not gain the advantage over you, but we protected you from the believers?" Allāh will judge between [all of] you on the Day of Resurrection, and never will Allāh give the disbelievers over the believers a way [to overcome them].1
Translation: Saheeh International (English)
1 In the Hereafter, but possibly in this world as well.
Those who wait to see what happens to you – whether good or bad; or if Allah gives you victory and gains of war – say, ‘Were we not present together with you?’ in order to get some gains of war. If the disbelievers have some success, they say to them, ‘Did we not protect you from and defend you against the believers by assisting you instead of them’. Allah will judge between all of you on the Day of Judgement: rewarding the believers by giving them entry into Paradise and the hypocrites by sending them to the lowest level of the fire of Hell. Allah, in His grace, will never give the disbelievers the upper hand over the believers. Instead, the believers will be the winners in the end.
