The ruling on praying the two rak'ahs of greeting the mosque while the imam is delivering the sermon

Question:
This questioner, who used the code name Abu 'Abdullah from the Eastern Region, says: Honorable Shaykh, a discussion took place between me and some of the brothers who pray in our mosque in the neighborhood regarding the two rak'ahs when entering the mosque while the imam is praying. I ask you for a ruling on this matter. Is it permissible or not? Also, the brothers praying in that mosque follow the school of Imam Malik.

Answer:
Yes, if he enters while the imam is delivering the sermon, and the imam does not sit until he prays two light rak'ahs, because a man entered while the Prophet (peace and blessings be upon him) was delivering the sermon, so he said to him, "Sit down," and he sat, so he said to him, "Stand up and pray two rak'ahs." If someone from the scholars says that it is not prayed there during the time of the sermon upon entry, we say to him: This is a hadith of the Messenger of Allah (peace and blessings be upon him), and what is followed is the evidence. Imam Malik (may Allah have mercy on him) said, "We are all refuted and refuting, except the one in this grave," meaning the Messenger of Allah (peace and blessings be upon him). So when the hadith comes, no one's opinion is valid. This hadith is before us, and it is authentic that whoever enters while the imam is delivering the sermon does not sit until he prays two light rak'ahs.
