Zikr & Dua

Using a zikr counter

Q: Alhamdulillah I use a counter to make zikr. Generally I meet alot of people of different races, cultures, etc. All of them ask the same question. "What's the counter for?" Could you please advise me what to tell them. Something that'll be simple but InshaAllah a means of hidayaat for them. Something that'll attract them to Islam and create that love for Allah Ta'ala. 

Different pronunciations in the istikhaara dua

Q: In Istikhara dua in some books it says Faqdirhuli and waqdir liyal Khair with a kasra (zer) under the daal, in other books it says Faqdurhuli and waqdur liyal Khair with a dhamma (pesh) on top of the daal, are both correct?

If not, which one is correct, daal with a dhamma or kasra in both places?

Could you please write the whole Istikhara dua with the correct Harkat?

Reciting duas and Quraan in a bathroom without a toilet

Q: A person has a bathroom with a sink, shower, etc. The toilet is enclosed in a shower door type enclosure. So the rest of the bathroom is not considered the toilet. Would it be correct to recite duas etc. there when making wudhu? Will it be fine to take a Quran inside the bathroom, recite Quran there whilst watching children in the bath? Not in the toilet, but in the rest of the bathroom.
