The ruling on reciting Surah al-Sajdah and Surah al-Insan in every Friday prayer

Question:
May Allah reward you, Honorable Shaykh. A questioner says: It is reported in a narration by al-Tabarani that the Prophet (peace and blessings be upon him) would consistently recite Surah al-Sajdah and Surah al-Insan. The question is: Is reciting them in every Friday prayer a recommended practice (sunnah), or does he sometimes leave them out?

Answer:
Sometimes. The meaning of "consistently" is "mostly," because if he did it in every single Friday prayer, people would think it is obligatory. Yes, in fact, some people believe that the Friday prayer has a prostration (sujud), and if the imam does not prostrate, he has left a recommended practice, is that not so? The prostration is not intended specifically for the Friday prayer; rather, it follows the recitation. When he recited a surah containing a prostration, he prostrated following the recitation. It is not for the sake of the Friday prayer, but for the sake of the recitation that contains a prostration. Yes.
