“Allah did not create man so that he could have fun. The aim of creation was for mankind to be put to the test through hardship and prayer. An Islamic regime must be serious in every field. There are no jokes in Islam. There is no humor in Islam. There is no fun in Islam. There can be no fun and joy in whatever is serious.” — Ayatollah Khomeini

“Firecrackers are un-Islamic, says Deoband-based cleric,” Times of India, October 18, 2019 (thanks to The Religion of Peace):

Meerut: A cleric based in Deoband town of Saharanpur has issued a fatwa against firecrackers calling them un-Islamic ahead of Diwali.

Maulana Abdul Wakeel Qasmi, state secretary, Ittehad Ulema-I-Hind, said, “Not only bursting firecrackers is un-Islamic but even profit earned from the business of firecrackers is haraam (prohibited).”

“What others are doing is none of our concern, but for Muslims, it is certainly haram. Bursting crackers is nowhere mentioned in our religious texts. To burn crackers is like burning your own money. This money can be used for better things like education,” Qasmi further stated.

Notably, Muslims in India burst firecrackers on Shab-e-Barat. Besides, a large number of Muslims are engaged in manufacturing firecrackers across the country….
