What is the ruling of placing the mushaf on the ground next to you, would it be haram or makrooh and what is the adab we should have with the mushaf?
Shaykh Ibn Baz was asked similar question :
Q : If I am reciting the Qur’an and I reach an Ayah (Qur’anic verse) requiring Sujud (prostration), is it permissible for me to place the Mus-haf (Qur’an, the Book) on the ground until I perform Sujud-ul-Tilawah (Prostration of Recitation), or should I place it on something raised above the ground?
A : There is nothing wrong in placing it on the ground when performing Sujud-ul-Tilawah, provided it is clean. If possible, it is better to place it on a raised area or give it to someone next to you until you perform Sujud, because this is one of the manifestations of honoring and glorifying it, and so that people do not think you intend to show disrespect or little care. May Allah grant us success.

Shaykh Ibn Uthaymeen was asked :
Q : What is the ruling of placing the Mus-haf on carpet in Masjid, some people have ruled that placing it (on ground on carpet) leads to Kufr ?
A : There is no problem and no issue if it is kept (on carpet) in a manner not dishonoring it like placing in front or on side, there is no problem and no issue in that and it is not kufr. But if he keeps in front his feet – no believer does that – then that is without doubt dishonoring the speech of Allah.
ما حكم وضع المصحف على الأرض فوق فرش المسجد فقد أفتى بعضهم بأن وضعه يؤدي إلى الكفر؟
فأجاب رحمه الله تعالى: لا بأس به ولا حرج فيه إذا وضعه على وجه ليس فيه إهانة مثل أن يضعه بين يديه أو إلى جنبه فإن ذلك لا بأس به ولا حرج فيه وليس بكفر أما لو وضعه بين قدميه وحاشا لأحد أن يفعل ذلك وهو مؤمن فهذا لا شك أنه إهانة لكلام الله عز وجل
