Recital prostration (sujud At-Tilawah) is to prostrate after reciting certain Qur’anic verses that refer to or command sujud. This can be done by the person who recites and whoever listens to him. Ibn `Umar reported that the Prophet (peace and blessings be upon him) used to read Qur’an, and whenever he read a surah which contained a prostration, he would prostrate and we would prostrate with him so that some of us could not find a place to lay their forehead.
With regard to your question, The Standing Committee for Islamic Research and Ifta’ states:
Some scholars regard sujud at-tilawah as a form of prayer, and on this basis they say that it is essential to be in a state of purity, to face the qiblah, to say Takbir when going down and when sitting up, and to say Tasleem after the prostration. Other scholars say that it is an act of worship, but it is not like prayer, and on this basis they say that it is not essential to be in a state of purity, to face the qiblah, and so on, as stated before. This is the more correct opinion, because we do not know of any evidence to suggest that being in a state of purity and facing the qiblah are essential, but if it is easy to face the qiblah when doing the prostration and to be in a state of purity, then this is better, so as to avoid dispute and to be in accordance with all the scholars.
