How does the caller proceed in calling a mushrik (one who associates partners with Allah) to Islam?

Question:
The questioner says: When I call a mushrik (one who associates partners with Allah) to Islam, and I start with tawhid (the oneness of Allah), do I proceed gradually with him regarding the other matters of the religion, such as prohibiting him from drinking khamr (intoxicants) and committing zina (unlawful sexual intercourse), or do I leave him as he is until his heart is at ease with Islam?

Answer:
Proceed gradually with him. Proceed gradually with him. Do not forbid him from drinking khamr (intoxicants) and remain silent about the shirk (associating partners with Allah) he has. Start with the shirk. Start with the shirk. Do not forbid him from khamr (intoxicants) until he is upright in tawhid (the oneness of Allah). If he is upright in tawhid (the oneness of Allah), proceed gradually with him in forbidding shirk (associating partners with Allah) and forbidding sins. Yes, start with the most important, then the next most important. Yes.
