Surah 25. Al-Furqan, Ayah 63

Sc., "with the aim to ridicule them or to argue against their beliefs".

Ignorant: in a moral sense. Address: in the aggressive sense. Their humility is shown in two ways: (1) to those in real search of knowledge, they give such knowledge as they have and as the recipients can assimilate; (2) to those who merely dispute, they do not speak harshly, but say "Peace!", as much as to say, "May it be well with you, may you repent and be better"; or "May Allah give me peace from such wrangling"; or "Peace, and Good-bye; let me leave you!"
