Salaah

Performing salaah with a thin scarf

Q:

1. When I tie a scarf around my head to pray, it sometimes moves or my hair can be seen through the material or my shoulder or neck can be seen through as it is slightly (not very) see through because of this I feel my prayer has been invalidated. Is this true? I of course wear clothes under the scarf but if the scarf is slightly see through, will this invalidate my namaz?

2. All the namaz I have been reading with this scarf, so if my namaz is invalid, would this mean my nikah would be invalidated?

Yawning in salaah

Q:

1. I covered my mouth with my hand when I was yawning during salah but quickly put my hand down.

2. The next time I yawned I believe I just stopped reciting and let it happen.

3. In another salah, I yawned, however I continued reciting as I yawned.

Are my salah’s fine?

What should I do if I yawn in salah?

Second jamaat

Q:

1. There is a masjid inside a university where many Muslim students live, but it often does not have any jamaat on Sundays, though Friday prayer is held there. An imam is appointed for the masjid, but he often does not come for fajr, isha and prayers on weekends (maybe because he lives far from the university). Is it correct to start a 2nd jamaat after the imam has already led the 1st jamaat in Salaah?

2. Is it correct to offer Friday prayer in this mosque?

3. I led a 2nd jamaat in this masjid, but after I started, I heard someone else leading another jamaat in the corner of the masjid. I did not know this before I started. Will I and my muqtadi's have to repeat the Salaah?
