Hazrat Abu Wa'il narrates that Hazrat Umar gathered the companions and consulted them regarding the number of takbirs in the funeral prayer. Some of them said that the Holy Prophet (peace and blessings be upon him) used to recite five takbirs, some said he used to recite seven takbirs, and some said he used to recite four takbirs. The narrator says that then all of them agreed upon four takbirs.
