Salaah

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?

Joining a masbooq in Salaah

Q: I am a follower of the Shaafi'i mazhab. In our musjid, which is mainly Shaafi'i the Somalian brothers will join a masbooq who has missed a few raka'ats and they will then follow the masbooq as if he is the Imaam.

1. Is this correct? If yes how should it be done.

2. What should you do if you are the masbooq and someone taps your shoulder or just joins your Salaah to follow you? Your input in this regard is greatly appreciated.
