(34) بَابٌ في كَمْ يُقْرَأُ الْقُرْآنُ
Narrated Sufyan:
Ibn Shubruma said, "I wanted to see how much of the Qur'an can be enough (to recite in prayer) and I could not find a Surah containing less than three Verses, therefore I said to myself), "One ought not to recite less than three (Quranic) Verses (in prayer)."
