He—may Allah have mercy on him—was asked:

“May missed regular sunnah prayers be made up?”

He answered:

If a regular sunnah prayer, such as the sunnah prayer associated with Zuhr, is missed, may it be made up after ‘Asr? There are two views, both reported from Ahmad:

The first is that it is not to be made up. This is the position of Abū Hanīfah and Mālik.

The second is that it is to be made up. This is al-Shāfi‘ī’s view, and it is the stronger view. Allah knows best.

He—may Allah have mercy on him—was asked:

“What about someone who does not consistently observe the regular sunnah prayers?”

He answered:

If someone persists in abandoning them, this indicates a lack of religious commitment, and his testimony is rejected according to the schools of Ahmad, al-Shāfi‘ī, and others.
