Issue 594: When Ihtiyat prayer becomes obligatory,
like in the case of the doubt between 3 and 4,
one must, without violating the figure of praying,
or without doing things which invalidate
prayers, stand up, make the intention for offering
such prayers, say the Takbeerat-ul-Ihram and offer Ihtiyat prayer, without pronouncing Adhaan and Iquamah.

Issue 595: The differences between Ihtiyat prayer and other prayers are as follows:

1- The intention must not be verbalized.

2- It does not have the Quranic chapter recited after the Al-Hamd; nor does it have any personal supplications, even when it is offered in two Rak'ats.

3- As an obligatory precaution, the Al-Hamd must be recited quietly but it is recommended to pronounce the "bis millahir Rahmanir Rahim" loudly.
