The Holy verse says:
"Muhammad is the apostle of Allah. and those who are with him are strong against disbelievers, (but) compassionate amongst each other. Thou wilt see them bow and prostrate themselves (in prayer), seeking Grace from Allah and (His) Good Pleasure. On their faces are their marks, (being) the traces of their prostration. This is their similitude in the Taurat; and their similitude in the Gospel is: like a seed which sends forth its blade, then makes it strong; it then becomes thick, and it stands on its own stem, (filling) the sowers with wonder and delight. As a result, it fills the Unbelievers with rage at them. Allah has promised those among them who believe and do righteous deeds forgiveness, and a great Reward." (48:29)
Mostly when I see this holy verse alleged as a verse of violence in the Holy Quran I find that they who falsely claim that do not write the complete verse and take only part of it like saying:" Muhammad is the Messenger of Allah ; and those with him are forceful against the disbelievers, merciful among themselves." and claim that this is discrimination between Muslims and non-Muslims. So now you can see the whole verse let's first explain the verse.
Then let's keep in mind the following notes:
1- The Arabic word mentioned in the Holy Quran is “ashidda” which does not mean ruthless as some people claim, but strong and firm. Ruthless is an incorrect translation.
2- The disbelievers mentioned in the verse means those who fought the Muslims and who persecuted and attacked them. How can you show leniency to someone who is attacking you for no reason except your faith.
3- Don't ignore the part of the verse saying:" This is their similitude in the Torah; and their similitude in the Gospel ", meaning that these same characteristics apply for the believers anywhere, anytime whether they are Muslims, Christians or Jews believers and this similitude is mentioned in the Bible and the Torah so why can you possibly consider it violent in the Quran but not in the Bible or the Torah.
And if this applies to any believer why and how can this possibly be considered discrimination based on religion if the verse says that these are the characteristics of ANY believer (that's why their characteristics are mentioned in the Torah, Bible and Quran) be him Muslim, Christian or Jew or any other believer in The one and Only God.
4-When the verse says: "On their faces are their marks" This does not imply the mark that appears on the forehead of some people on account of prostrations, but it implies the marks and traces of the fear of God, munificence, nobility and goodness of manner that naturally appears on the face of a person on account of bowing down before God.
What Allah means to say is: The companions of Muhammad (peace be upon him) are such that one can recognize them on first sight, because their faces shine forth with the light of God worship and God consciousness. This is the same thing about which Imam Malik has said that when the armies of the companions entered Syria, the Syrian Christians remarked: These people possess the very same qualities and characteristics of the disciples of the Prophet Jesus Christ (peace be upon him).
5. A similar example is found in a sermon of the Prophet Jesus, peace be upon him, that has been reported in the New Testament, thus:
And he said, So is the kingdom of God, as if a man should cast seed into the ground: And should sleep, and rise night and day, and the seed should spring and grow up, he knoweth not how. For the earth bringeth forth fruit of herself; first the blade, then the ear, after that the full corn in the ear. But when the fruit is brought forth, immediately he putteth in the sickle, because the harvest is come. And he said, Where unto shall we liken the kingdom of God? Or with what comparison shall we compare it? It is like a grain of mustard seed, which, when it is sewn in the earth, is less than all the seeds that be in the earth. But when it is sown, it groweth up, and becometh greater than all herbs, and shouted out great branches; so that the fowls of the air may lodge under the shadow of it. "
The last portion of this sermon is also found in Matthew, 13: 31-32.
