Bleeding After Nifaas

Q: A woman had 40 days of nifaas. Then there was no bleeding for two days. Thereafter she started to bleed. What would this new bleeding be? Would it be istihadha or haiz? Also, if it was haiz, would it be counted according to the old habit the one before she got pregnant?

Bleeding in Pregnancy

Q: I am pregnant Alhamdullilah and last week I had some bleeding. Alhamdullilah the bleeding stopped but now I am unsure if I can begin reading my Salaah as there are still some black flaky discharge. My underwear remains clean and I can only see the discharge when I go to the toilet. Can I make ghusal and start reading my Salaah or should I wait until the discharge is gone completely.
And please can you suggest a dua that I can read to keep my unborn baby safe and that my baby grows healthy, normal, strong and pious.

Doubting after Discharging the Zakaat

Q: Recently I went for Haj Alhamdulillah. I had taken my zakaat money with me to distribute to the poor in Makkah and Medinah. I had given the zakaat to the cleaners of the Haram in Makkah & Medinah. Someone told me that the cleaners collect a lot of money from others whilst others informed me that they are poor. I am not sure which category do they fall under. Please let me know if my zakaat will be fulfilled or do I need to re-take out zakaat?

Repentance after Apostasy

Q: If a believer commits an act of kufr which renders him a murtad thereafter he repents, will that repentance be accepted or not? E.g. Someone spoke bad of Nabi (Sallallahu Alayhi Wasallam) so he became a murtad thereafter he repented, will that particular sin of kufr be forgiven or not?
