You should not give away a part of your prayer to Satan by thinking that it is necessary to depart (after finishing the prayer) from one's right side only; I have seen the Prophet ﷺ often leave from the left side. (Using translation from Bukhārī 852)
لَا يَجْعَلْ أَحَدُكُمْ لِلشَّيْطَانِ نَصِيبًا مِنْ صَلَاتِهِ يَرَى أَنَّ حَقًّا عَلَيْهِ أَنْ لَا يَنْصَرِفَ إِلَّا عَنْ يَمِينِهِ لَقَدْ «رَأَيْتُ رَسُولَ اللَّهِ ﷺ كَثِيرًا يَنْصَرِفُ عَنْ يَسَارِهِ»
