Sajdah-e-Tilaawat

Q: When you read a Surah and you reach a place where you have to do sajdah, is it obligatory and is it a sin if you don't do it? Because if you are reading it by heart in bus or public places how will you do it?

Q: During which times of the day is it impermissible to perform previous sajdah-e-tilaawah?

Q: Is it permissible to perform a sajdah tilaawat starting standing up and finishing sitting down? What about starting sitting and finishing standing. I understand starting standing and finishing standing is mustahab. Sitting and finishing sitting is also fine.

Q: If I am learning a Surah with a sajdah off by heart, then do I have to do the same amount of sajdah tilawat as the amount of times I recite the aayat of sajdah? If I am making more than one sajdah tilawat then how would I do it? Is it the same as in namaz or do I have to do them all separately with intentions in between all of them because I have quite a few to do from before as well?

Q: I read Surah Alaq in salaah. I did sajdah tilawat and got up from sajda to qiyaam position. Now the question is, can I go into ruku immediately or should I pause for a while in the qiyam position?

Q: Is it permissible to do 14 sajda tilawaahs at one time after completion of the recital of the qur'aan or a person has to do it in fours? That is 4, 4 sajdahs at a time?

Q: Is one able to perform sajda-e-tilaawat between asar and maghrib?

Q: Is it permissible to read all the sajdah tilawat after completing the entire quran or do we have to read our sajdah tilawat as soon as I read the ayah of sajda?

Q:

1. Does Sajdah Tilawat have to be commenced from a standing position or can it be done straight from a sitting position?
2. When completing the Sajdah Tilwat does one have to stand up after the Sajdah or is it ok to complete the Sajdah by returning to the sitting position?

Q: When one hears an aayah of sajdah being recited over the receiver, does one have to make sajdah?
