The Instructions

LXXIX.—To the Petitioners. If thou desirest, when praying, to be heard from heaven, break the chains from the lurking-places of wickedness; or if, pitying the poor, thou prayest by thy benefits, doubt not but what thou shalt have asked may be given to the petitioner. Then truly, if void of benefits, thou adorest God, do not thus at all make thy prayers vainly.
