Please find enclosed a 70+ page - pdf file i put together in the last few days in response to one who calls himself at times by the Kunya - "Abu Alqama" at the well known forum of fitna and fasad known as - ah.ya.org.
This individual has posted here in the past under various screen names and is probably the most anti-Hanafi writer on the internet in the english language to date. The file contains a reply to his claims of grave worship, unwarranted attacks and weakening of a narration regarding the following that our brother Faqir documented here with this wording:
NARRATION OF MALIK AL-DAR
Imam al-Bayhaqi relates with a sound (sahih) chain:
It is related from Malik al-Dar, `Umar's treasurer, that the people suffered a drought during the successorship of `Umar, whereupon a man came to the grave of the Prophet and said: "O Messenger of Allah, ask for rain for your Community, for verily they have but perished," after which the Prophet appeared to him in a dream and told him: "Go to `Umar and give him my greeting, then tell him that they will be watered. Tell him: You must be clever, you must be clever!" The man went and told `Umar. The latter said: "O my Lord, I spare no effort except in what escapes my power!"
"Ibn Kathir cites it thus from Bayhaqi in al-Bidaya wa al-nihaya and says: isnaduhu sahih; Ibn Abi Shayba cites it in his Musannaf with a sound (sahih) chain as confirmed by Ibn Hajar who says: rawa Ibn Abi Shayba bi isnadin sahih and cites the hadith in Fath al-bari. He identifies Malik al-Dar as `Umar's treasurer (khazin `umar) and says that the man who visited and saw the Prophet in his dream is identified as the Companion Bilal ibn al-Harith, and he counts this hadith among the reasons for Bukhari's naming of the chapter "The people's request to their leader for rain if they suffer drought." He also mentions it in al-Isaba, where he says that Ibn Abi Khaythama cited it."
