Show me proof where you can hold your own birthday gatherings? Quran and Sunnah conferences? Seerah conferences? Proof where you can hold rallies against the governments? Darnas against the government? Show me proof where Prophet peace be upon him stated you can make Quran in to one book? Prove how you compile Sahih Bukhari, Sahih Muslim in to a book? Show me proof where you make large beautiful mosques? Show me proof where you make your houses in to palaces? Did Prophet peace be upon him lived like this? Proof where you hold weekly and monthly tajweed gatherings?
The point is if all these other gatherings are fine then a Mawlid gathering is also fine. Islam and Quran and Sunnat does not forbid gatherings?
In the UK many people who burn at seeing a Mawlid gathering hold Quran parties, they hold eid gatherings in park and organise food festivals, Mela gatherings with swings, rides for children. Prove this from sunnah?
Exactly, people love to hold many forms of political gatherings and they dont need proof for that. They hold many forms of quran and sunnah gatherings but dont need proof? They hold weekly and monthly tajweed gatherings and dont need proof, they hold Eid ul Fitr and Eid ul Adha parties and dont need proof? They hold Islamic summer camps, Islamic summer walks for charity, Islamic weekend gatherings, Islamic 5 days Ijtima conference and dont need proof.
But only on Mawlid gathering they need proof and use Microscope to check the evidence.
