The Messenger of Allah ﷺ said, "Whoever recites the Quran in less than three days has not understood it."

قال رسول الله ﷺ من قرأ القرآن في أقل من ثلاث لم يفقهه
Its isnad is sahih. The man from whom Qatada narrated is one of two people, Yazid bin Abdullah bin Shikhir or Abu Ayub Muraghi, and his reliability has already been established at 6750. The uncertainty does not matter, since it is a shift from one reliable narrator to another reliable narrator. The hadith is an abridgment of 6775, from the narration of Qatada from Yazid bin Abdullah bin Shikhir.
