The holy Koran (Quraan shareef) consists of verses called aayat-e-sajdah, verses of prostration, on which it is obligatory to prostrate (make a sajdah) at the end either after having read or listened the verse.
One should prostrate as we usually do in namaz (swalaat) by starting with the standing posture and by finishing it in the same way, i.e. in the standing position. In clear, if the aayat-e-sajdah is being read during namaz, we automatically perform the sajdah in the namaz, but when are reading the Quraan shareef while seated, we must put the Quraan aside, stand up to perform the sajdah (from standing to standing) and after the sajdah, sit down again to continue to read the Quraan. However, if we are reciting the Quraan by heart (without wazu) or whilst walking or doing another action, we can postpone the sajdah for later on but it remains faraz (obligatory) on us (lifetime).
However, a student who is learning the Quraan by heart (making haafiz) can recite an aayat-e-sajdah several times to be able to memorize it but will owe only one sajda-e-tilaawat.
During the sajdah (prostration) one should read the same wazifah (recitation) as during namaz i.e. 3 (or 5) times “subhaana rabbiyal a’laa” (Glory to my Lord the very high). These verses of prostration are of 14 in the holy Koran with this small precision that the Hanafis do not perform the one which is marked with one * whereas the Shafi’is do not perform the one which is marked with two **, see the list hereafter:

SEASONSALI 
please change the name of the surah an najl to surah nahal
Jazakallah. This is the first time I’m learning what Sajdah means. I would have just followed the leader and done sajdah, but never even questioned anyone why we did it and what it was for. I’m asking forgiveness from Allah SWT and thank my brother in law for mentioning and introducing this word ‘Sajdah’ in conversation.
please do the correction surah HaaMeem sajdah is in jun no 26 not in juz no 24
There are only 14 sajdas mentioned in the quran kindky remove the 11th sajdah as the surah mentioned above is wrong the surah’s name is saafat not swaad and there is no sajdah in this surah. Stop spreading false things about the book of Allah and this is the thing where no one can make mistake. Do not just go with the other sources on google check in the book of Allah and verify.
Kindly add Sajda duwa also….
Sajada wajhiya lillazee khalaqahoo wa sawwarahoo; wa shaqqa sam’ahoo wa basarahoo; Fatabaarak-Allaahu Ahsanul-Khaaliqeen. (At-Tirmidhi 2/474, Ahmad 6/30, and Al-Hakim)
If this dua is not remembered means than only we can recite Subhaana Rabbiyal aala, if not the main Dua is the lengthy one actually.
