Do not belittle people who seemingly lack of knowledge but instead strive to guide them with love and compassion..
Knowledge by itself is not only useless but may be a mortal trap that leads to Satanic pride. Neither the proud nor the ignorant are excused; yet the loving, sincere, and repentent Sufi who suffers even severe gaps in his knowledge and adab is closer to Allah Most High and to knowledge of Allah than the knowledgeable Sufi who harbors a speck of pride in his heart. May Allah protect you and us!
Ibrahim al-Khawwass said knowledge is not to know much but to obey the Sunna and practice what one knows even if a little. Imam Malik said knowledge is not to know many things but is a light Allah casts in the heart.Imam al-Shafi'i said knowledge is not to know proofs but to know what is beneficial.And when someone said of Ma'ruf al-Karkhi, "He is not very knowledgeable," Imam Ahmad said: " Mah! Allah forgive you! Is anything meant by Knowledge other than what Ma'ruf attained?!"
