Is it permissible to make up the 'Asr prayer before Maghrib?

The Shaykh : The questioner says: If I miss the 'Asr prayer, is it permissible for me to make it up before Maghrib? Yes, it is permissible for a person to make up an obligatory prayer that he missed before Maghrib, based on the saying of the Prophet (peace and blessings be upon him) So whenever you remember a missed obligatory prayer, you make it up. The questioner says: Is it permissible for us to prolong the prostration and not rise with the imam, doing so in the first rak'ah for supplication and seeking forgiveness from Allah, and then we rise, recite al-Fatihah, and follow the imam's recitation?
