These verses distinguish quarreling from legitimate discussion. They condemn disputing without knowledge, which is mere wrangling, and disputing with falsehood to refute the truth, which is bound to fail, while acknowledging that dispute is part of human nature; they lay down the etiquette of debate, conducted in the best manner, and mention the disputes of the dreadful Day.
Verses gathered from a topical index of the Quran, in Mushaf order; every verse is quoted in full.
Invite to the way of your Lord with wisdom and good instruction, and argue with them in a way that is best. Indeed, your Lord is most knowing of who has strayed from His way, and He is most knowing of who is [rightly] guided.
For every [religious] community We have appointed rites which they perform. So, [O Muḥammad], let them [i.e., the disbelievers] not contend with you over the matter but invite [them] to your Lord. Indeed, you are upon straight guidance.
And do not argue with the People of the Scripture except in a way that is best, except for those who commit injustice among them, and say, "We believe in that which has been revealed to us and revealed to you. And our God and your God is one; and we are Muslims [in submission] to Him."
