Salaah

Sajda-e-sahw

Q: Can you please explain uptil when sajda-e-sahw can be done for unintentionally missing out a wajib in the prayer? If a person unintentionally leaves out a wajib, and they have done salaam, can they still do sajda-e-sahw? Also, if a person does not do sajda-e-sahw, and the prayer time has ended, will they have to redo the prayer? I have heard that the prayer will have to be redone for leaving out a sajda-e-sahw as long as its still the prayer time, but after the prayer time has passed, it is not mandatory to redo the prayer, but recommended to. Please if you can explain.

Travelling without a mahram

Q: Is it allowed for a lady to travel with her child of age one year for umra. Her husband is in Saudi Arabia and will be waiting in Jeddah airport for her and also will perform umra with her, but she will be alone in travelling from Pakistan to Saudi Arabia airport. I hear it is mandatory for her to have a mahram with her. My question is, is it ok for her to travel alone to Saudi and after that perform umra with her husband?

Walking in front of the person performing Salaah

Q:

1. If a person walks directly in front of you, within a arms reach, in a masjid kabeer, should you restart the Salaah?

2. What about a small masjid?

3. Will the ruling change if the person was walking from in front, stepped directly onto your sajdah spot, walked towards you then pushed through touching your shoulders, but technically didn't cross in front from one side to the other?
