Zikr & Dua

Reward for reciting a certain durood

Q:

اللهم صل على سيدنا محمد ما اختلف الملوان وتعاقب العصران وكر الجديدان واستقبل الفرقدان وبلغ روحه وارواح اهل بيته منا التحية والسلام

Whoever recites this durud thrice, will receive the reward of reciting salutations 30 000 times. Can one make such statements? Mawlana mentioned in accordance to tajrabah of a dream. He didnt say it was a hadeeth. Also, can one have such aqeedah that by doing such, it will happen.

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?
