Please explain who is allowed to give Da'wah.

Answer

Da'wah means to invite others to Islam or to offer good Islamic advice to anyone on any issue. Teaching one's children is also Da'wah. All forms of Deeni advice given to others is Da'wah. Self-reformation is not a condition for Da'wah. Just as Salaat, Fasting, Charity, Hajj, etc. are acts of ibaadat, so too is Da'wah. All acts of ibaadat have to be compulsorily performed regardless of the moral and spiritual status of a person. Similarly, Da'wah is an ibaadat which has to be upheld by even a person who is not a practising Muslim. If every person has to wait for the achievement of moral purification, the avenue of Da'wah will close. No one knows whether he has attained a sufficient degree of self-reformation to regard himself / herself as purified and qualified for Da'wah. The feeling that one has not achieved moral purification, hence not entitled to make Da'wah is a nafsaani deception. Whenever the opportunity occurs, one should engage in Da'wah. However, the Da'wah of a non-practising person will be devoid of barkat. People will not derive true benefit from him.
