Question:
What advice do you have for Muslims who use the Gregorian months?
Answer:
I advise them to… It is obligatory for Muslims to use the lunar months, just as the Prophet (peace and blessings be upon him) and his Companions (may Allah be pleased with them) used them. If there is a need for the solar months, there is no harm in adding them to the lunar ones, saying, for example, “such-and-such day, corresponding to such-and-such day.” If there is a need for the nights of the other months, he adds them to the lunar months. However, using them alone is not allowed; a Muslim does not use them alone, but mentions both. Yes.
