Salaah

Q: If a na baaligh girl has not read asr salaah and thereafter she reads at sunset is it better for her to complete the salaah or to break the salaah?

Q: When reading salaah behind an imam, what does one read in the standing position (does the person following read surah fatiha and a surah)?

Q:

1. Can Qadha salaah (esp. Qadha Umri) be performed after the fardh of fajr and asr? If so then what salaah are not permitted at that time?
2. On safar, a person does not perform a salaah e.g. asr. On returning home from the journey, does one perform qasr (i.e. 2 rakaats qadah) or 4 rakaats of qadah?
3. Likewise, if a person omits a salaah e.g. asr in his hometown, whilst on safar does the person perform 4 rakaats of qadah or 2  rakaats of qadah for the salaah missed whilst still at home?

Q: In the posture of qiyaam, should a woman join her feet together or should there be a gap of four fingers between her feet, as is the case of men?

Q: In the posture of qiyaam, where should a woman place her hands? Should she place her hands below her chest or on her chest?

Q: In the massajid in Makkah and Madinah, there are no sahen areas. The second jamaah is performed in the musjid area. Should we join such a jamaah if we have missed the first jamaah?

Q: Can you explain how sajda-e-sahw is done in the Hanafi Mazhab?

Q: When should the muqtadi start to change posture in salat (e.g. from qiyam to sajdah): should he start moving immediately when the imam starts saying "Allahu akbar" or should he wait until the imam has completed saying the whole phrase "Allahu akbar"? Or should he, if he can see the imam, wait until the imam has totally completed his change of posture.

Q: If someone keeps his books or study materials (secular) open in his study table containing pictures of animated objects then if he prays Salaah in that room, will it be valid. (If he stands for Salaah then his study table will be by his right side and it will be sufficiently far to go unnoticed).

Q: Yesterday, when I went to toilet, I found stains of pre-cum (mazi) [I have this problem that often it comes out unintentionally). The stain was very small, probably smaller than a drop of water. Nevertheless, as I was in a hurry to join the Asr Salah in jamah, I forgot to change my underwear and even forgot to wash the stain. In this condition I prayer the Asr, Mugrib, Esha and todays Fajr Salah before recalling the incident. Now my question is should I repeat the four Salah prayed in the above mentioned condition or was my Salah valid. Can you also advise me on what to do for the problem of the mazi coming out.
