One should keep in contact even with someone who acts wrongly
Question
A certain man wears a kurta (long shirt) whose skirt covers the buttocks — sometimes over a waist-cloth, sometimes over an izar; has his sleeves made only up to the elbows; has his beard shaved below the throat and above the cheeks and always keeps it shorter than a fist. Then there is his way of performing wudu in the ablution tank, washing each limb three times each; he does not give his sisters their share; he wears a red Turkish cap (fez)
Answer
One should keep in contact with him and continue to reform him with gentleness and compassion.
