The Ruling on Following the Adhan

Question:
Honorable Shaykh, one came and delayed the other mu'adhdhin, so you did not follow them. You are required to follow only one.

Answer:
Follow the one closest to you whose adhan you hear clearly, provided they all call to prayer at the same time; following one of them is sufficient, and it should be the one closest to you. However, if they call to prayer one after another, following all of them is better and yields more reward. If they are calling one after another, follow each one in order to obtain a great reward. Even if you limit yourself to following just one, that is sufficient. The more you follow, the greater the reward, because the Messenger (peace and blessings be upon him) said, "When you hear the mu'adhdhin..." This indicates that whenever you hear a mu'adhdhin, you follow him, and you must seek to obtain the great reward. Yes. This includes the adhan on the radio; the adhan on the radio falls under this ruling.
