Going late to the Musjid for zuhr Salaah

Q: I am at home and the zuhr prayer jamat will soon start in the masjid and I have only a few minutes to perform my 4 sunnats. If I perform the sunnats before I leave for the masjid, I will miss the beginning of the jamat (I will catch the last 1-2 rakats). Should I do this, or should I instead leave early to the masjid and pray the 4 sunnats after the fard, thus catching the jamaat from its beginning?

How will a person suffering from anal fissure perform Salaah?

Q: I am a mazoor suffering from urine incontinence. I keep tissue paper all the time in my underwear. Now I am suffering from anal fissure. Because of it, some pus comes out from the anal passage every time, so I am unable to keep wudhu and maintain my purity? I am already keeping tissue for incontinence of urine. I am really worried and leaving prayers. Please make an easy way for me.

Medical issues

Q: My question is regarding my daughter. She is currently 5 weeks old. When she was not born I decided to name her Khadijah but when she was born I changed her name to Anabiya. Since she has born till now she has something going on. First she had gas and when we changed her milk she was fine after that she got younger infection.

My question is that weather this is due to the fact that first her name since when she was not born our intention was a different name but after she was born we changed it. She also cries a lot can you please tell me a Surat or dua that I can read every time she cries? Can you respond to me as soon as possible as if I should change her name to Khadijah or leave it to Anabiya?
