Why do Muslims hasten to perform the funeral prayer?
This practice is on account of the directive of the Prophet (SAS) when he said, ‘three things must not be delayed, salaah when its time has arrived; the funeral prayer when the body is ready for burial; and the marriage of a girl when her match is found (recorded by Imam Tirmizi)
And Allah knows best.
