It is narrated from Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) that indeed the Messenger of Allah (peace and blessings be upon him) said: "O people! There should be no deception among Muslims. Whoever deceives us is not from us." And Muslim bin Hajjaj has also narrated it with his chain from Sayyiduna Abu Hurairah (may Allah be pleased with him) that indeed the Messenger of Allah (peace and blessings be upon him) said: "Whoever raises a weapon against us is not from us, and whoever deceives us is also not from us."
