Fath al-Rabbani

(Second Chain) Sayyiduna Abu Hurairah, may Allah be pleased with him, said: I met Sayyiduna Abdullah bin Salam, may Allah be pleased with him, and told him about my meeting with Ka'b, that he said this hour occurs once a year. He (Abdullah bin Salam) said: Ka'b has spoken incorrectly; rather, it occurs every Friday, as the Messenger of Allah, peace and blessings be upon him, has said. I said: Yes, he had retracted his statement. Then he (Abdullah bin Salam) said: By the One in whose hand is the soul of Abdullah bin Salam! I know this hour very well. I said: O Abdullah! Then tell me. He said: It is the last hour on Friday. I said: But regarding this, the Messenger of Allah, peace and blessings be upon him, said that any believer who supplicates in it, while he is in the state of prayer (and at that hour, no prayer is performed). He said: Have you not heard the saying of the Messenger of Allah, peace and blessings be upon him, that the one who waits for the prayer is considered to be in prayer, as long as he does not pray? I said: Why not, he said: Then that is the matter.
