Q: I received a message posted on social media about a Durood Sharif Majlis at a Darul Uloom during which a person present in the Majlis had a vision of Nabi Sallallahu Alayhi Wasallam telling him that it was his desire that such Majalis should take place everywhere. A scholar who was present there and to whom this was narrated stated that it was his heart's desire that Durood Sharif Khatams should be established in all Darul Ulooms.I know of a Darul Uloom where such a Khatam takes place.

Q: I hope you are doing good. I have a question about ayat e karima. I was born and raised in South Asia so people over their have gatherings where they finish 125000 times ayat e karima. I have heard many times that you need to finish it 125000 times for a specific problem. I am going through some extremely serious problems of my life. I have two questions.

1. I am reading ayat e kareema all night from 12:00am-fajar and finishing 11000 times daily. I have heard that if I finish it in 40 days Insha Allah my troubles and problems will be gone by the blessing and mercy of Allah. I wanted to confirm the authenticity of the number.

2. The second and last question is one of the aamils told me that if I will read it so much, it's so jalali that it can also harm me or make me crazy or something and I am like how Allah's ayah can drive someone crazy. Zikr is always a source of relief and peace. How could that be please guide me here.
