we cited above that Allah (Glorified and Exalted be He) says: And We made from among them (Children of Israel), leaders, giving guidance under Our Command, when they were patient and used to believe with certainty in Our Ayât (proofs, evidence, verses, lessons, signs, revelations, etc.).
O Allah's Servant, be patient in your Da`wah, have firm faith, good deeds, and be sure of all your deeds. Have a deep insight, seek religious knowledge, and act on clear proof! By doing so, your Da`wah will be based on patience and certainty and you will be a leader and a good example to all people regarding your good deeds and good behavior. These are the merits and virtues of Da`wah.
