The ruling on praying the greeting of the mosque during the prohibited times

Question:
And among the obligations is what is valid due to the difficulty of performing the duty of many believers at a time when there is no sadness.

Answer:
So there is disagreement, and it is not blameworthy for one who performs it, nor is it blameworthy for one who leaves it, because there is disagreement in this issue. Also, it is a recommended practice (sunnah), not an obligation. It is permissible to perform the recommended practice, and it is permissible to leave it. One who performs it gets reward, and one who leaves it owes nothing. The matter is broad, and praise be to Allah. Some of the brothers used to be strict about this and declare innovators those who pray the greeting of the mosque at the time of prohibition, pushing them away. No, this is not permissible. It is a matter of disagreement, and it is a place of independent legal reasoning (ijtihad) and consideration based on the texts, because the texts differ: texts of prohibition and texts of command. Some scholars prioritize the texts of command, and some prioritize the texts of prohibition. It is a matter of disagreement, and each has a point of view. Also, the issue is recommended; this sunnah is recommended. Is it not obligatory?
And even if the scholars agreed on performing it at the time of prohibition, and it is recommended, it is permissible, because the recommended is permissible, so there is no blame in it.
