Salaah

Not waking up for fajr 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.

Mazi coming out while one is leading the Salaah

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?

Countries which have six months day and six months night

Q: It has been some time ago that I had read something in Ma'aariful Quraan of mufti Shafi' sb (RA) and I just cannot remember in which volume it appears. The discussion was on the namaaz times in those countries where they have six months day lite and six months night. First time I had read that explanation and I'd like to read it again but just cannot find it. Will it be possible to let me know under the tafseer of which aayat I will be able to find it?
