Salaah

Q: A musaafir joined a muqeem imam in a 4 rakaat salaah. His wudhu broke, so he had to leave. So when he repeats the salaah must he read 2 rakaats qasr or should he perform full 4 rakaats?

Q: Please advice if a lady has a long dress or abaya on that is not see through must she still wear a pants underneath when praying namaaz?

Q: If in "Ihdeenas-Siratal-Mustaqeem", I recited dee with a daad mistakenly instead of daal does this invalidate the namaz? I don't know for sure if I done it, but it seems likely so should I repeat the namaz or is it an acceptable mistake? I didn't repeat it afterwards.

Q:During tashahhud one says "..as salaamu alayna ayyuhan nabiyyu" instead of "..as salaamu alayka ayyun nabiyyu". Does this mistake invalidate salaah?

Q: It was narrated that Abu Sa’eed al-Khudri (may Allaah be pleased with him) said: A woman came to the Prophet (peace and blessings of Allaah be upon him) when we were with him and said: “O Messenger of Allaah, my husband Safwaan ibn al-Mu’attal does not pray Fajr until the sun has risen.” Safwaan was with him, so he asked him about what she had said, and he said: “O Messenger of Allaah, we are a family who are known not to wake up until the sun has risen.” He said: “When you wake up, then pray.” Narrated by Abu Dawood, 2459; classed as saheeh by Shaykh al-Albaani in Irwa’ al-Ghaleel, 7/65. 

I can't pray fajr salah because I have sleep problems.  I don't fall asleep easily and if I wake up for fajr I can't fall asleep again so can I pray fajr at zuhr time, would it be valid and am I a kafir if I don't pray fajr on time. Above hadith it says our prophet allowed a man to pray fajr after sunrise.

Q: While leading the salaah, I had a feeling that mazi may have been discharged, but was not sure. When I returned home, I found a slight wetness
at the tip of my private area, and it was only when I began to clean it that the mazi began come out. Now I am uncertain if it remained in the passage 
during salaah and began to come out as a result of walking, or if any came out during salaah. Firstly, will it be necessary for the congregation to repeat the salaah? Secondly, is this common, or is it a medical issue?

Q: While using perfume, will namaz not be accepted? If this is true then what will happen with our past namaz because I use perfume and spray every time and offer prayer in it?

Q: In farz namaz is it right to correct the Imam if he reads the wrong ayah?

Q: My son is 6 months old, during salaah I lay him on the floor. If I see he is in danger as in choking during making Fard salaah what do I do?

Q: I am working in a warehouse. There are two cats here. I took care of them when they were 2 days now they are at 6 months. They play with me and jump on me. I just wanted to know that I have only one uniform at the same time in that uniform can I offer prayer?
