It is narrated from Sayyiduna ‘Itban (may Allah be pleased with him) that once I presented myself before the Prophet (peace and blessings be upon him) and said: My eyesight is weak and there is this valley and darkness between me and you, so if you could come at some time and pray in my house, I would select that place as my prayer area. The Prophet (peace and blessings be upon him) promised me to do so. Accordingly, one day the Prophet (peace and blessings be upon him) came with Sayyiduna Abu Bakr and ‘Umar (may Allah be pleased with them). When the Ansar heard of this, they began to come to visit the Prophet (peace and blessings be upon him), but one man, whose name was Malik bin Dukhsh, was left behind and people already used to accuse him of hypocrisy. The people stayed until the time of food and began to talk among themselves. In the course of conversation, they said: He knows that the Prophet (peace and blessings be upon him) has come to us, but he has stayed behind only because of his hypocrisy. At that time, the Prophet (peace and blessings be upon him) was praying. When he finished the prayer, he said: Alas! Does he not sincerely bear witness to "La ilaha illallah"? Whoever bears witness to this statement, Allah has made the fire of Hell forbidden for him.
