Question: As salam alaykum,
1- Is it permitted to include the two sunna units (rak`ats) after the Maghrib prayer in the units for the Prayer of the Oft-Repentant (awwabin)?
2 – With the remaining 4 units of the Prayer of the Oft-Repentant can one pray 4 units of a makeup prayer?
Answer: Wa alaikum assalam wa rahmatullahi wa barakatuh,
I pray that this message finds you well, insha’Allah.
(1) Yes, it is permitted to include the two sunna units (rak`ats) after the Maghrib prayer in the units for the Prayer of the Oft-Repentant (awwabin), which are six in number.
(2) It is permissible to combine the intentions of a makeup prayer with that of non-confirmed sunna prayers.
Please see: Is It Valid to Combine Multiple Intentions in One Prayer?
And Allah alone knows best.
