BismilLaahir Rahmaanir Raheem
Amongst what the Muslim scholars stated also in this regard is that the one who finishes answering the call of nature and leaves the restroom (bathroom/toilet) should say: “Ghufraanaka (I seek Your forgiveness).”
That is because this was reported from the Messenger of Allaah, peace and blessing be upon him, and Ibn Khuzaymah, Ibn Hibaan and Al-Haakim deemed it Saheeh in the compilations of Imam Abu Dawood may Allah be pleased with him.
It means I seek your forgiveness for such thing that made me busy from remembering You and thus one finishes it with invocation in much the same way he starts it.
Also, his saying in the second Hadeeth: ("If anyone of you goes to an open space for answering the call of nature he should neither face nor turn his back towards the Qibla (i.e. the direction of Ka‘bah).
As for his saying, "If anyone of you goes to an open space for answering the call of nature…, it means if one sits down to answer the call of nature he should not face nor turn his back towards the Qiblah. This is related to the people of Madeenah (i.e. Medina) because the Qiblah is at the south of it. As for who is not from the inhabitants of the Madeenah, he should turn away from the direction of the Qiblah. This prohibition is to show respect and glorification for the Ka‘bah. But if your home toilet is fixed to face the kaaba and you cannot change it, that's ok as the walls serve as sutra for the qiblah and ALLAH knows best.
May ALLAH keep guiding us all and protect us from any satanic influences. AMIN
