A sufi, a salafi, a tablighi jamaati and a hizb-u-tehriri are chilling out enjoying a pizza together.

Suddenly, the light bulb goes out and in the pitch black an argument breaks on what to do.

The TJ speaks up first; "Brothers, I think we should make a jamaat, elect an amir and read Fazail-e-Amaal together for guidance".

"And how you gonna read bro?" said the HT, "There's no light. We must first establish a khilafa state and the Caliph will decide how to rectify the situation."

"No, no. You're both wrong" interrupts the sufi, "The 4 of us will hold a dhikr gathering and the noor from the dhikr will light up the room."

The 3 of them start arguing again and then fall silent and look at the salafi; "Well. What do you think we should do?" they all ask him.

"Brother", replies the salafi, "Where's your daleel for the light bulb?"
