After evoking the Name of ALLAH (The Glorified, The Exalted) and the prayer and the peace upon the Messenger of ALLAH,
I exhort and advise you to fear ALLAH (The Glorified, The Exalted), both in secret and in public, to purify your heart from any opposition to His Order, to rely on ALLAH with your heart, to accept His decisions in all circumstances, to bear the hardships of the paths that He decrees in all situations, and, for this, depend on abundant evocations, with the Presence of the Heart as much as possible, this will help you to follow my advice.
Know that the greatest evocation of ALLAH, for the benefit that it brings, the most efficient and advantageous, is the prayer upon the Messenger of ALLAH (peace and blessings be upon him) with the presence of the heart. This prayer takes care of all requests, both in this world and the next, to repel and attract in all matters. He who recites it profusely will become one of the greatest and sincere friends of ALLAH (The Glorified, The Exalted).
The second thing that I exhort you to do is to renounce using money that is declared illegal by the Law, for food, clothing and lodging, because that which is lawful is the pole around which all the stars of adoration orbit. He who turns away from that which is lawful will also have turned away from all the benefit related to adoration. Beware of saying: “But where is it to be found?” Certainly, it does exist abundantly in every land and in every age, but you will only find it having sought to perfectly fulfil the commandments of ALLAH, both interiorly and exteriorly; and considering the requirements of the moment, if we cannot find what is undoubtedly lawful, then a scrupulous knowledge of jurisprudence is required in this domain as well as a wide knowledge of the prescriptions of the Law. He who conforms to this, will have no difficulty finding that which is lawful.
