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?
