Question: I hope to be a daa’iyah, so what is your advice to me?
Response: We hope that Allaah facilitates your hopes, and we advise you to seek knowledge and act according to it, and call to it (the knowledge, i.e. Islaam) with that which is best, and [with] good intention and [to have] patience at what befalls you whilst doing so (i.e. calling to Islaam).
And with Allaah lies all success and may Allaah send prayers and salutations upon our Prophet (sal-Allaahu ‘alayhi wa sallam) and his family and his companions.
