20th Ayah from Surah Al 'Imran
Sahih International
So if they argue with you, say, "I have submitted myself to Allah [in Islam], and [so have] those who follow me." And say to those who were given the Scripture and [to] the unlearned, "Have you submitted yourselves?" And if they submit [in Islam], they are rightly guided; but if they turn away - then upon you is only the [duty of] notification. And Allah is Seeing of [His] servants.
Abdul Haleem
if they argue with you [Prophet], say, ‘I have devoted myself to God alone and so have my followers.’ Ask those who were given the Scripture, as well as those without one, ‘Do you too devote yourselves to Him alone?’ If they do, they will be guided, but if they turn away, your only duty is to convey the message. God is aware of His servants.
Mohsin Khan/Hilali
So if they dispute with you (Muhammad SAW) say: "I have submitted myself to Allah (in Islam), and (so have) those who follow me." And say to those who were given the Scripture (Jews and Christians) and to those who are illiterates (Arab pagans): "Do you (also) submit yourselves (to Allah in Islam)?" If they do, they are rightly guided; but if they turn away, your duty is only to convey the Message; and Allah is All-Seer of (His) slaves.
Taqi Usmani
Then, if they argue with you, say: “I have submitted myself to Allah, and (so did) those who have followed me.” And say to those who have been given the Book, and to the unlettered: “Do you submit?” If they submit, they will be on the right path. Yet, if they turn back, then you have only to convey the message. Allah is watchful over (all of) His servants.
Pickthall
And if they argue with thee, (O Muhammad), say: I have surrendered my purpose to Allah and (so have) those who follow me. And say unto those who have received the Scripture and those who read not: Have ye (too) surrendered? If they surrender, then truly they are rightly guided, and if they turn away, then it is thy duty only to convey the message (unto them). Allah is Seer of (His) bondmen.
Pickthall
So if they dispute with thee, say: "I have submitted My whole self to Allah and so have those who follow me." And say to the People of the Book and to those who are unlearned: "Do ye (also) submit yourselves?" If they do, they are in right guidance, but if they turn back, Thy duty is to convey the Message; and in Allah's sight are (all) His servants.
