Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) narrates that the Prophet (peace and blessings be upon him) said: "Hold back from the people of 'La ilaha illallah' (there is no god but Allah), and do not declare them disbelievers because of a sin. Whoever declares the people of 'La ilaha illallah' to be disbelievers is himself closer to disbelief."
Al-Tabarani recorded it in al-Mu'jam al-Kabir; its chain mentions that al-Dahhak bin Humrah narrated it from Ali bin Zayd, and there is disagreement about using the two of them as evidence.
