What is the ruling on the greeting prayer of the mosque during a time of disapproval?

Question:
This is a question about the greeting of the mosque, the prayer of greeting the mosque after the 'Asr prayer. This is a matter of disagreement among the scholars regarding the greeting of the mosque: is it performed during the prohibited times or not?

Answer:
Is it performed? There are two opinions, and one does not criticize the one who performs it, nor does one criticize the one who leaves it off. First, because it is a sunnah (recommended practice), not an obligation, and it is permissible to perform a sunnah and permissible to leave it off. It is a sunnah. Second, there is disagreement regarding this time. So, if one follows those who say the prayer is performed and prays, there is no harm. And if one follows those who generalize the prohibition, there is no harm. There is no criticism of either side, because the issue is a matter of scholarly consideration.
