A treatise on the rulings of menstruation and post-natal bleeding, and issuing fatwas to people based on what one has heard

Question:
A questioner says: I am a man from outside this country, and the people of my country have a good opinion of my character, so they come to me to ask about matters of knowledge. I do not answer them except with what I have heard from the scholars in this country, and what I hear from the program *Nur 'ala al-Darb*. However, there is a matter my family asks me about, which concerns issues of menstruation, post-natal bleeding, and irregular bleeding, and other matters specific to women. It would be wonderful if you would be generous, may Allah reward you with good, and compose a clear and comprehensive treatise on these important topics.

Answer:
There are long and short compiled hadiths available on menstruation, post-natal bleeding, and the rulings of ritual purity. As for what you mentioned about giving people rulings based on what you hear from scholars or the radio: if you are hesitant about answering and issuing fatwas, you should tell them, "I heard so-and-so the scholar say this, I heard the radio say this." Mention to them that you heard this or read this, and cite it. Do not give them the ruling and remain silent, for they will assume the fatwa is from your own country. Rather, say, "This is something I heard or read." Clarify to them that it is not your own opinion. As for the questions you are overwhelmed with, refer them to the scholars, write to the scholars, ask those who have access to the scholars, and ask them.
