Q: I wanted to ask that If I recite surah al alaq in the day without reading it from the Quran, do I have to do sajdah?

Q: If someone,while doing hifz did not make all the sajdah tilawats after reading ayaat of sajdah and now does not have any idea of how many (sajda tilawah) were not made,what should be done?

Q: If a sajdah aayah is heard in the state of haidh or janaabat, will the sajdah still be wajib on a person?

Q: If a hanafi Imaam recites an Aayat of sajdah (that is according to Imam shaafi'ee Rahimahullah and not according to Imam Abu Hanifah Rahimahullah e.g: The Aayat of sajdah that appears at the end of the 17th juz) in salaah, and he is followed by muqtadis of the different mazhaahib, then what should he do in this situation. If he doesn't make sajdah will their salaah be valid? Is there a solution to this?

Q: If a person is reading the translation of the Qur'aan in English or Urdu and he reads the translation of an aayah of sajdah, then is it necessary for him to perform sajdah-e-tilaawah, just as it would have been necessary if he had recited the aayah in Arabic?
