Silsilat al-Ahadith al-Sahihah

Sayyiduna Bara’ (may Allah be pleased with him) narrates that an Ansari man came to the Prophet Muhammad (peace and blessings be upon him) armed with weapons and said: “O Messenger of Allah! Should I fight or accept Islam?” The Prophet (peace and blessings be upon him) said: “No, rather accept Islam first, then fight in jihad.” He accepted Islam, then participated in jihad and was martyred. The Messenger of Allah (peace and blessings be upon him) said: “He performed (a little) action and received a great reward.”

It is narrated from Sayyiduna Abu Hurairah, may Allah be pleased with him, that the Noble Prophet, peace and blessings be upon him, said: "At the beginning of leadership there is blame, at its end there is regret and remorse, and on the Day of Resurrection there is punishment."

Sayyiduna Anas bin Malik (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: "It is necessary for people to have a leader, (but) the leader is in the Hellfire."
