Silsilah as-Sahihah 3749 — Heresy in the Sanctuary Is a Grave Sin

Sayyiduna Sa'id bin 'Amr (may Allah be pleased with him) narrates that Sayyiduna 'Abdullah bin 'Amr (may Allah be pleased with them both) came to Zubair (may Allah be pleased with him) while he was sitting in Hatim. He said: Ibn Zubair! Beware of deviation in Allah's Sacred Sanctuary. I bear witness that I heard the Messenger of Allah (peace and blessings be upon him) say: "A man from Quraysh will deem Makkah and the Sacred Sanctuary of Makkah lawful and permissible. If his sins are weighed against the sins of jinn and mankind, his sins will outweigh them." O Ibn 'Amr! Reflect and ponder, lest you be that man. You have recited the Qur'an and kept the company of the Messenger of Allah (peace and blessings be upon him). He said: I make you a witness that my face is towards Shaam; I am going for jihad.
