Is reciting Surah al-Sajdah and Surah al-Insan in the Fajr prayer on Friday considered lengthening the prayer?

Question:
Some people say that if you pray Fajr in congregation on Friday with Surah al-Sajdah and Surah al-Insan, you have lengthened the prayer. Is this considered lengthening?

Answer:
No, this is acting in accordance with the Sunnah, and it is not lengthening. But this is laziness; the one who tells you this is being lazy. So do not pay attention to him. If you act in accordance with the Sunnah, do not pay attention to those who oppose you in this. It is not lengthening to recite Surah al-Sajdah and Surah al-Insan. The Prophet (peace and blessings be upon him) used to recite in Fajr from seventy to one hundred verses (peace and blessings be upon him). He would enter the prayer while a man did not know who was next to him because of the darkness, and he would not leave it until the man knew his companion. He used to lengthen the prayer (peace and blessings be upon him). Allah (Mighty and Majestic) says: meaning the Fajr prayer, which He called "recitation" because the recitation in it is lengthened. Yes.
