Hadith 1401
Narrated Amr ibn al-As: The Prophet ﷺ taught me fifteen prostrations while reciting the Quran, including three in al-Mufassal and two in Surah al-Hajj. Abu Dawud said: Abu al-Darda has reported eleven prostrations from the Prophet ﷺ, but chain of this tradition is weak.
Hadith 1402
Narrated Uqbah ibn Amir: I said to the Messenger of Allah ﷺ: Are there two prostrations in Surah al-Hajj? He replied: Yes; if anyone does not make two prostrations, he should not recite them.
