Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates: The Noble Prophet (peace and blessings be upon him) said: "It is obligatory upon you to perform prayer behind every Muslim, whether he is righteous or sinful, even if he commits major sins. And it is obligatory upon you to perform jihad with every leader, whether he is righteous or sinful, even if he commits major sins. And it is obligatory upon you to perform the funeral prayer for every Muslim who passes away, whether he is righteous or sinful, even if he commits major sins."
