Question: I miss my fajr, how does one do a make up the correct way? The time of sunrise where i live is at 6:30. I sometimes get up at 6:20.

Answer: Although one can perform salaah 5 to 7 minutes before sunrise, to do so would count as a valid prayer, however, with great dislike. It would be better to perform the prayer then not performing the prayer at all.

Should you not have time to perform it upon getting up, merely do so after sunrise. You could perform your sunnah that was missed and your fajr salah thereafter.

However, should you not make it up after sunrise, in such a situation merely make up only the missed fard later on without its missed sunnah.

May we all become steadfast upon our obligations, Ameen

Allah Certainly Knows Best.
