Musannaf Ibn Abi Shaybah

Hazrat Abu Marthad narrates that I was with Hazrat Abu Dharr Ghifari near the middle Jamarah. I asked him about the Night of Qadr, so he said: I used to ask the Messenger of Allah (peace and blessings be upon him) the most about the Night of Qadr. One day I submitted, "O Messenger of Allah! The Night of Qadr used to occur in the times of the Prophets; when the Prophets departed from this world, this night was also taken away. Is it so?" He replied, "No, rather the Night of Qadr will remain until the Day of Resurrection." I submitted, "O Messenger of Allah! Then please inform me about it." He said, "If I were permitted to inform you about it, I would surely have told you. However, I will say this much: seek it in one of the last seven nights of Ramadan. Now do not ask me about this matter." After that, the Messenger of Allah (peace and blessings be upon him) became engaged in other matters. When I sensed happiness in his blessed disposition, I submitted, "O Messenger of Allah! I beseech you by oath to tell me about this night." Upon hearing this, the Messenger of Allah (peace and blessings be upon him) became so angry with me that I had never seen him so angry before or after.
