You offer a prayer which I did not see being offered by Messenger of Allah ﷺ when we were in his company and he certainly had forbidden it (i.e. two rakʿat after the ʿAsr prayer). (Using translation from Bukhārī 587)
إِنَّكُمْ لَتُصَلُّونَ صَلَاةً لَقَدْ صَحِبْنَا رَسُولَ اللهِ ﷺ فَمَا رَأَيْنَاهُ يُصَلِّيهَا وَلَقَدْ نَهَى عَنْهُمَا يَعْنِي الرَّكْعَتَيْنِ بَعْدَ الْعَصْرِ
