Q: Is the following authentic to be read at the time of azaan: 

مَرْحَبَّا بِالْقَائِلِينَ عَدْلاً مرْحَبًا بِالصَّلَوةِ وَأَهْلاً

Khateeb Baghdadi (rahimahullah) reports in a narration that Nabi (sallallahu alaiyhi wasallam) has said that whoever says the above the moment the Muazzin proclaims the Azaan; 20 000 virtues are written down for him; 20 000 sins are forgiven; and 20 000 ranks are elevated for him. (Jaamia Al Hadeeth, As-Suyuti, Pg 313, Vol 7)

Q: Our area masjid is closed due to renovation. We now perform Salah at two temporary venues. We have one azan that is given from the masjid that is closed, and no azan from the temporary musallahs. 

Is this correct? What is the status of azan?

Q: Is there an authentic Hadith stating that fasting on the day of Arafah equals the fasting of 2 years (as appears in Tanbeehul Ghafileen, baab 39, fadlu ayyaamil ashri)?

Q: Is the shape of the forearms and calves of a woman required to be concealed infront of non mahrams? 

Also, what about the upper half of the forearms and lower half of calves, as the shape might be exposed if the abaya sleeves fall down or the dress goes up due to wearing tight sleeves and leggings (to conceal skin)?

Q: If a person, due to slip of tongue, said something of kufr while not intending it, is he kafir? 

For example, a person wanting to say that "one who rejects God is not a Muslim" but he accidentally says "one who rejects God is not a kafir" but then he realises and corrects it. Does he have to renew his iman and nikah?

Q: If a dua recommended in the Hadith for a particular purpose is said in a congregational form (نا), should the individual reciting it change it and say it in individual form (ني)?

Q: I had istihadha but not a mazoor. I placed cotton wool like a khursuf but only after completing my umrah and coming out of Ihraam I saw that it messed through. What will I do?

Q: There is a couple that recently came from hajj. They did all things correct but they have 1 doubt. 

After coming from Muzdalifah, doing 1st rami, and cutting of hairs/halaq, they opened their ihram and after that they thought they are open from ihram and out of ignorance and oversight they did sexual relations just before tawaf e ziarat. 

Tawaf e ziarat was done after gusal and proper clean cloths? Would they be required to give damm? If yes, will it be for both or just 1?

Q: I am in company who is selling a product for 2300 and I am dealing with the employee of the company. He is telling me to make the invoice for 2400 and after the transaction has been made then give him secretly 100 dollars.  

Is this permissible for me to give secretly? 

Q: I've been asking Allah to make me friends with a non mahram. Its been a lot of time now I see no signs of my dua getting accepted. I am really confused if this is prohibited thats why its not getting accepted or somewhere I found we can be friends with a non mahram with boundaries so if its permissible then why is Allah not accepting it. I've looked up everywhere and I still remain in an utter state of confusion. I cry for this dua every prayer, every rain, every azaan yet its not being accepted. I really don't know if I should wait or give up. If this is right or wrong. Please help me.
