The prayer is valid.

If I forget to say Rabana Walakal Hamd after Samey Allahu leman Hameda will my prayer be accepted.

Jazakallah Shaikh for the prompt reply but my question remains unclear, my question is sometime I am late in the Zohar prayer and I manage to pray only 2 Rakat and join the Fard prayer,can I pray the 2 +2 after Zohar, is this fine. Apologies for any inconvenience in my English language.

If a person wakes up and finds that there’s only a few minutes left before the time for Fajr finishes, should they pray the two Rak’ah Sunnah first (because of it’s virtue) and then pray the two Rak’ah Fardh knowing that the time may have left or should they just pray the two Rak’ah Fardh immediately?
