Assalamu alaikum Ustadh. Is it true that one (even without a legitimate reason) prays Asr just before Maghreb (after the yellowing of sun) has still caught up with salah, (but still sinful )due to a Hadith in this regard. Jazakallahu Khairan

Ustadh AbdulAziz al-Haqqan

It is not allowed to pray at that time except for a necessity.
