Is it necessary to repeatedly offer advice to relatives and others for prayers to be answered, and does the obligation of advising cease with the existence of educational bodies and institutions?

Enjoining good and forbidding evil is essential for society. It is contingent upon ability, and consideration must be given to benefits and harms. Messages and pamphlets can be used to confront evils. Repeating advice varies according to individuals and circumstances. Do not fall short in supplication; it is an act of worship, and a good deed is recorded for a Muslim if he supplicates and his prayer is not answered.
